Exoplanet discoveries

[edit]

Main article: Sarah Ballard

She took part in the discovery four exoplanets before she turned 30 years old, including Kepler-19c, the first exoplanet found using the transit-timing variation method on data from the Kepler mission.[1][2][3]

Note: There is no scientific consensus about terrestrial composition of most of the planets in the list. Sources in the "Main source" column confirm the possibility of terrestrial composition.

In September 2012, the discovery of two planets orbiting Gliese 163[37] was announced.[38][39] One of the planets, Gliese 163 c, about 6.9 times the mass of Earth and somewhat hotter, was considered to be within the habitable zone, but is probably not terrestrial.[38][39] In May 2016, the finding of three earth-like planets of ultracool dwarf TRAPPIST-1 has been released.
