Kepler-10b is the first confirmed terrestrial planet to have been discovered outside the Solar System by the Kepler Space Telescope. [7] Discovered after several months of data collection during the course of the NASA-directed Kepler Mission, which aims to discover Earth-like planets crossing in front of their host stars, the planet's discovery was announced on January 10, 2011.
Kepler-10, formerly known as KOI-72, is a Sun-like star in the constellation of Draco that lies 607 light-years (186 parsecs) from Earth. [5] [6] Kepler-10 was targeted by NASA's Kepler space telescope, as it was seen as the first star identified by the Kepler mission that could be a possible host to a small, transiting exoplanet. [7]
[82] [83] However, despite having been described as a "tenth planet" in an early NASA press release, [84] Eris (then known only as 2003 UB 313) is now classified as a dwarf planet. Only slightly more massive than Pluto, [85] Eris has a well-determined orbit that never brings it closer to Earth than 5.5 billion km (3.4 billion mi). [86]
By Irene Klotz BOSTON (Reuters) - Astronomers have discovered a new type of rocky planet beyond the solar system that weighs more than 17 times as much as Earth while being just over twice the ...
Soon afterwards, a NASA Jet Propulsion Laboratory press release described the object as the "tenth planet". [60] Eris was never officially classified as a planet, and the 2006 definition of planet defined both Eris and Pluto not as planets but as dwarf planets because they have not cleared their neighbourhoods.

NASA's OSIRIS-REx mission found ingredients for DNA and RNA on the asteroid Bennu. The discovery shows asteroids could seed planets with the precursors for life. It's also more evidence that life ...
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 ...
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 ...
