Kepler-444 (or KOI-3158, KIC 6278762, 2MASS J19190052+4138043, BD+41°3306) [10] is a triple star system, estimated to be 11.2 billion years old (more than 80% of the age of the universe), [12] approximately 119 light-years (36 pc) away from Earth in the constellation Lyra.
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.
The planets in the Kepler-444 system have radii of 0.4, 0.497, 0.53, 0.546 and 0.741 Earth radii, respectively. Due to their size and proximity to Kepler-444, these must be rocky planets, with masses close to that of Mars .
This is a list of unconfirmed exoplanets discovered or detected by the NASA Kepler mission (Kepler Candidates from the NASA Exoplanet Archive) that are potentially habitable. [1] [2] Those already confirmed are listed by their Kepler names in the list of potentially habitable exoplanets, and the data may differ when the planets are confirmed ...

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 ...
This artist's visualisation of WASP-127b, a giant gas planet located about 520 light-years from Earth, shows its newly discovered supersonic jet winds that move around the planet's equator.
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.
