A star system known as TRAPPIST-1 has three potentially Earth-like planets in its orbit. This is an artist's impression of the TRAPPIST-1 star system as seen from one of the three alien planets.

It orbits around its host star with a period of 207.5 days, comparable to Earth's one-year period," Gu added. ... "It demonstrates the potential of the TTV technique to detect low-mass planets in ...

The young sun may have captured several Mars- or Mercury-size exoplanets that now orbit in the outer reaches of the solar system, but identifying them will be extremely challenging.

Using data from NASA's planet-hunting Kepler telescope, scientists have estimated that one in every four sun-sized stars has an Earth-like planet orbiting it.; That translates to about 10 billion ...
