A rogue planet (also termed a free-floating planet (FFP), interstellar, nomad, orphan, starless, unbound or wandering planet) is an interstellar object of planetary-mass which is not gravitationally bound to any star or brown dwarf.[1][2][3] Rogue planets originate from planetary systems in which they are formed and later ejected. They can also form on their own, outside a planetary system. The Milky Way alone may have billions to trillions of rogue planets, a range the upcoming Nancy Grace Roman Space Telescope will likely be able to narrow down.[4][5]
Astronomers have used the Herschel Space Observatory and the Very Large Telescope to observe a very young free-floating planetary-mass object, OTS 44, and demonstrate that the processes characterizing the canonical star-like mode of formation apply to isolated objects down to a few Jupiter masses. Herschel far-infrared observations have shown that OTS 44 is surrounded by a disk of at least 10 Earth masses and thus could eventually form a mini planetary system.[8] Spectroscopic observations of OTS 44 with the SINFONI spectrograph at the Very Large Telescope have revealed that the disk is actively accreting matter, similar to the disks of young stars.[8] In December 2013, a candidate exomoon of a rogue planet (MOA-2011-BLG-262) was announced.[9]

Astrophysicist Takahiro Sumi of Osaka University in Japan and colleagues, who form the Microlensing Observations in Astrophysics and the Optical Gravitational Lensing Experiment collaborations, published their study of microlensing in 2011. They observed 50 million stars in the Milky Way by using the 1.8-metre (5 ft 11 in) MOA-II telescope at New Zealand's Mount John Observatory and the 1.3-metre (4 ft 3 in) University of Warsaw telescope at Chile's Las Campanas Observatory. They found 474 incidents of microlensing, ten of which were brief enough to be planets of around Jupiter's size with no associated star in the immediate vicinity. The researchers estimated from their observations that there are nearly two Jupiter-mass rogue planets for every star in the Milky Way.[13][14][15] One study suggested a much larger number, up to 100,000 times more rogue planets than stars in the Milky Way, though this study encompassed hypothetical objects much smaller than Jupiter.[16] A 2017 study by Przemek Mróz of Warsaw University Observatory and colleagues, with six times larger statistics than the 2011 study, indicates an upper limit on Jupiter-mass free-floating or wide-orbit planets of 0.25 planets per main-sequence star in the Milky Way.[17]
In September 2020, astronomers using microlensing techniques reported the detection, for the first time, of an Earth-mass rogue planet (named OGLE-2016-BLG-1928) unbounded to any star and free floating in the Milky Way galaxy.[19][20][21]
In December 2021, the largest ever group of rogue planets was discovered, numbering at least 70 and up to 170 depending on the assumed age. They are found in the OB association between Upper Scorpius and Ophiuchus with masses between 4 and 13 MJ and age around 3 to 10 million years, and were most likely formed by either gravitational collapse of gas clouds, or formation in a protoplanetary disk followed by ejection due to dynamical instabilities.[22][23][24][25]
Interstellar planets generate little heat and are not heated by a star.[26] However, in 1998, David J. Stevenson theorized that some planet-sized objects adrift in interstellar space might sustain a thick atmosphere that would not freeze out. He proposed that these atmospheres would be preserved by the pressure-induced far-infrared radiation opacity of a thick hydrogen-containing atmosphere.[27]
During planetary-system formation, several small protoplanetary bodies may be ejected from the system.[28] An ejected body would receive less of the stellar-generated ultraviolet light that can strip away the lighter elements of its atmosphere. Even an Earth-sized body would have enough gravity to prevent the escape of the hydrogen and helium in its atmosphere.[27] In an Earth-sized object the geothermal energy from residual core radioisotope decay could maintain a surface temperature above the melting point of water,[27] allowing liquid-water oceans to exist. These planets are likely to remain geologically active for long periods. If they have geodynamo-created protective magnetospheres and sea floor volcanism, hydrothermal vents could provide energy for life.[27] These bodies would be difficult to detect because of their weak thermal microwave radiation emissions, although reflected solar radiation and far-infrared thermal emissions may be detectable from an object that is less than 1,000 astronomical units from Earth.[29] Around five percent of Earth-sized ejected planets with Moon-sized natural satellites would retain their satellites after ejection. A large satellite would be a source of significant geological tidal heating.[30]
The table below lists rogue planets, confirmed or suspected, that have been discovered. It is yet unknown whether these planets were ejected from orbiting a star or else formed on their own as sub-brown dwarfs. Whether exceptionally low-mass rogue planets (such as OGLE-2012-BLG-1323 and KMT-2019-BLG-2073) are even capable of being formed on their own is currently unknown.
If we could slice Venus and Earth in half, pole to pole, and place them side by side, they would look remarkably similar. Each planet has an iron core enveloped by a hot-rock mantle; the thinnest of skins forms a rocky, exterior crust. On both planets, this thin skin changes form and sometimes erupts into volcanoes in response to the ebb and flow of heat and pressure deep beneath.
The broiling surface of Venus has been a topic of heated discussion among planetary scientists. The traditional picture includes a catastrophic, planetwide resurfacing between 350 and 750 million years ago. In other words, Venus appears to have completely erased most traces of its early surface. The causes: volcanic and tectonic forces, which could include surface buckling and massive eruptions. But newer estimates made with help from computer models paint a different portrait. While the same forces would be at work, resurfacing would be piecemeal over an extended time. The average age of surface features could be as young as 150 million years, with some older surfaces mixed in.
Since its launch, millions of players have downloaded the game, which brings in hundreds of millions of dollars in revenue to its creators every month. It was even big enough to score an official crossover with Avengers: Infinity War and Endgame (the latter was actually a two-way crossover).
Jump to the Surface Behind Atton there is a navigational chart that shows the Ebon Hawk's destination. Choose Telos and the next planet will come into view. A security crew will stop the crew and arrest them as witnesses to the destruction of the mining facility. When you are trapped in the force cages, a bounty hunter named Batu Rem will enter the facility to kill you and your allies. Blast him with force powers and he will quickly fall. Unfortunately, the facility officers do not believe your claims and must investigate the killing.
Inside Slusks office he asks what your motives are, and you reply that you simply want him dead. During this final conversation with Slusk, Luxa enters the room with her band of thugs. Do not threaten to kill her while intimidating Slusk or you will have to fight both of them at the same time. Instead, kill Slusk and then deal with Luxa. She will try to subdue you after the battle and another fight takes place. Kill her Gamorrean guards first, then focus your team on her. After the battle there are two containers and a footlocker in the room that can be searched. Speak to Kreia about her past to see a cinema involving her and other Sith. Then, ask her about constructing a lightsaber in order to become a more powerful member of the Sith and you will gain experience and dark side points. Czerka Offices AttackedSince you have completed the missions involving the exchange, return to the Czerka offices to find them being attacked by mercenaries. There are four mercenaries in the Lobby armed with blaster rifles. You can attack them through the walls with force lightning. Deeper into the offices there are four more mercenaries who are accompanied by two combat droids. Use the stun droid force power to get an edge on them. As you enter the main hall where Jana Lorso works you will face another group of mercenaries. After the battle, demand a reward from Lorso, then tell her that the exchange has been taken care of. She will reward your party with credits and inform you that a shuttle is waiting at docking bay 3 that will take you to the planet's surface. Leave the offices and take the lift to the cantina level. At docking bay three you can bribe the secretary behind the desk for information related to the Flase Batu mission. Before you leave, you will receive a crucial lightsaber fixture from the Duros behind the desk at the docking bay. Side Quests
When you enter the base, avoid the square in the center of the room because it emits poisonous gas. The door to the next area is shielded, so select Bao-Dur and select the bash option. He will use his prosthetic arm to open the door. The next room is filled with turrets that will fire on the party as soon as they enter the area. The center of the room is filled with noxious gas emission, so stick to the sides near the wall. In the center of the room there is a computer terminal where the turrets can be switched off and you can download a map of the facility. Continue through to the next force field using Bao-Dur and face three Telos Military Droids. In the halls of the next area. There are supplies hidden amongst a corpse at the end of the hallway to the left. The next room is filled with poisonous gas grates, so stick to the walls. Then disable the next force shield and fight three more military droids. Search the hallway straight ahead and the supply pack in the center of the next area. You will come across the first lightsaber crystal. Take a right down the next hallway where you will encounter more turrets. There are four turrets in this large area, and they are shielded so use anti shield weapons or force powers to take off large chunks of their health. After the room is cleared there is a workbench and a lab station on either side of the room. The next area contains the orbital shuttle. Unfortunately for you, the bay doors are locked and ship requires ignition pass codes. If you inspect the rear of the ship it will restore the party's health for no apparent reason. 2ff7e9595c
