Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth's Cousin [4] [5] based on its characteristics; also known by its Kepler object of interest designation KOI-7016.01) is a candidate [6] [7] super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system discovered by the Kepler space telescope.
Venus has been the prime example for a planet resembling Earth and how such a planet can differ. An Earth analog, also called an Earth twin or second Earth, is a planet or moon with environmental conditions similar to those found on Earth. The term Earth-like planet is also used, but this term may refer to any terrestrial planet.
Another Trans-Neptunian planet at 1,500 AU away from the Sun, proposed by Rodney Gomes in 2012 [20] Theia or Orpheus, [21] a Mars-sized impactor believed to have collided with the Earth roughly 4.5 billion years ago; an event which created the Moon. Evidence from 2019 suggests that it may have originated in the outer Solar System. [22]
Scientists have found a new Earth-like planet that could support alien life – just 40 light-years away.. The planet is a remarkable discovery in the search for habitable worlds: it is slightly ...
Seven Earth-sized planets have been discovered orbiting a nearby star, three of which appear to be warm enough to sustain life, according to astronomers from NASA and the European Southern ...

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 ...
This list of exoplanets discovered in 2019 is a list of confirmed exoplanets that were first observed during 2019. [1] [2] For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.
