Kepler has surveyed about 150,000 sun-like stellar systems in our galaxy and discovered over 1,000 alien planets.Is Life Special Just Because It’s Rare? - Issue 95: Escape | Alan Lightman | January 20, 2021 | Nautilus
Kepler might find thousands of new worlds, but it wouldn’t reveal enough of any single one of them for us to know whether it was somebody’s home.
In fact, Kepler pairs are miniature solar systems and Newton’s laws create them out of chaos.
Kepler surveyed over 150,000 stars, found more than 4,000 candidate exoplanets, and confirmed over 2,800.There Could Be 300 Million (or More) Earth-Like Planets in Our Galaxy | Jason Dorrier | November 8, 2020 | Singularity Hub
Kepler has identified over 2,800 exoplanets, only some of which orbit sun-like stars.Half the Milky Way’s sun-like stars could be home to Earth-like planets | Neel Patel | November 6, 2020 | MIT Technology Review
Kepler-10c, which is the proper name for the mega-Earth, orbits its star much closer than our planet does.
The planet was found via transit, and it is officially known as Kepler-186f.
Kepler-186f is about 11 percent larger than Earth in diameter, which means it has nearly 25% more surface area.
So, for us to know if Kepler-186f is habitable or not, we have to consider several “ifs”.
On Thursday, researchers announced the discovery of Kepler-186f, an Earth-like exoplanet orbiting in a “habitable zone.”

Scientific definitions for Kepler
German astronomer and mathematician who is considered the founder of celestial mechanics. He was first to accurately describe the elliptical orbits of Earth and the planets around the Sun and demonstrated that planets move fastest when they are closest to the Sun. He also established that a planet's distance from the Sun can be calculated if its period of revolution is known.
