New earth-size planet discovered By George Petras, Traci Watson, Mitchell Thorson ... It’s probably a rocky world close in size to Earth and has 1.3 times the mass of Earth or larger.

A new, Earth-sized planet has been discovered only 90 light-years away from us. In astronomical terms, that’s right next door. What’s more, it might be capable of supporting life.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has been used to discover Earth-size planet TOI 700 e. It is "orbiting ...

Astronomers have discovered an Earth-sized exoplanet orbiting a star with a lifespan 100 times greater than the Sun. Speculoos-3b is 55 light years away – more then 10 times further than the ...

The new planet is almost the same size as Earth and swings around its home star, which is called LP 791-18, about once every three Earth days. Average temperatures there could spike to more than ...

There’s a new Earth-size planet on the block, and it’s the closest potentially habitable world that orbits a “quiet” life-friendly star. Discovered just 11 light-years away, Ross 128b ...

The newfound exoplanet, called Kepler-139f, is a gigantic world roughly twice the mass of Neptune and 35 times the mass of ...

The newly discovered planet measures about 1.1 Earth radii, making it slightly larger than Earth, but researchers still think the alien world may be rocky like Earth.

Astronomers using NASA’s Kepler Space Telescope announced the discovery of the most Earth-like planet yet orbiting a distant star like our own sun, bringing to a dozen the number of small worlds ...

A potentially habitable Earth-size planet was discovered just 40 light-years away Dubbed Gliese 12 b, the planet takes 12.8 days to orbit a star that is 27% of the sun’s size.

Planet d is Earth-size, within the star’s habitable zone and orbits TOI-700 every 37 days. My colleagues wanted me to create a climate model for Planet d using the known properties of the star ...

Seven Earth-size planets, shown here in an artist’s stylized rendering, have been discovered orbiting a red dwarf star about 40 light-years away, scientists announced on Wednesday.
