Kepler-69c has gone through a similar process; though initially estimated to be potentially habitable, [69] it was quickly realized that the planet is more likely to be similar to Venus, [70] and is thus no longer considered habitable. [1] Several other planets, such as Gliese 180 b, also appear to be examples of planets once considered ...
Cosmic inflation expands space by a factor of the order of 10 26 over a time of the order of 10 −36 to 10 −32 seconds. The universe is supercooled from about 10 27 down to 10 22 Kelvins. [18] The strong interaction becomes distinct from the electroweak interaction. Electroweak epoch ends 10 −12 s 10 15 K (150 GeV)
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f As of 24 January 2025, there are 5,830 confirmed exoplanets in 4,354 planetary systems , with 976 systems having more than one planet .

The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
Two teams of scientists have discovered a theoretically habitable planet called Gliese 12b that’s smaller than Earth but bigger than Venus, just 40 light-years away.
The telescope has been hard at work scanning the universe for habitable planetary bodies ... "The planets, all between 20 and 50 percent larger than Earth by diameter, are orbiting the M dwarf ...
The most distant potentially habitable planet confirmed is Kepler-1606b, at 2870 light-years distant, [3] although the unconfirmed planet KOI-5889.01 is over 5000 light-years distant. On 31 March 2022, K2-2016-BLG-0005Lb was reported to be the most distant exoplanet discovered by the Kepler telescope, at 17 000 light-years away. [4]
