The Sun Will Destroy the Earth One Day, Right? Maybe Not. Astronomers spotted a potential Earth-size rocky world orbiting a white dwarf, suggesting a future in which our planet outlives its star.

Equatorial plane The Sun-Earth-Moon system are constantly at play, but Earth and its lunar satellite are a bit more intimate — with a center of mass, or barycenter, 2,900 miles (4,600 km) from ...

Astronomers have discovered a planet roaming in the Milky Way, orbiting a white dwarf. Around 1.9 times the mass of Earth, this planet likely supported life during its lifetime and orbited a host ...

As a result, the Earth is not currently orbiting a point inside the Sun, as the barycenter is outside of it. We are orbiting that point in space, rather than the Sun.

Each year the Earth takes 365 days to complete one successful lap around the Sun, but if the planet stopped orbiting, we'd only live for about a month.

Getting off Earth, away from the light pollution and atmospheric distortion of the ground, helps Hubble to provide some of the most pristine images of the universe to date.

We have discovered 30,039 near-Earth asteroids in the Solar System, most of which were discovered in the last decade.

Many astronomers think in 5 billion years, the sun will puff up and engulf Earth. But a new observation is challenging that prediction.
