ESO Discovers Earth-Size Planet in Habitable Zone of Nearest Star

The Kepler data suggest we should expect at least one potentially habitable, Earth-size planet orbiting M-type stars, like Proxima, within 10 light-years of our solar system. So the latest discovery was "not completely unexpected. We''re more lucky than surprised," Seager said. But it "helps buoy our confidence that planets are everywhere."

Mercury

Mercury is the smallest planet in our solar system and the nearest to the Sun. Mercury is only slightly larger than Earth''s Moon. Its surface is covered in tens of thousands of impact craters.

Solar System Facts

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed. Nearest to the Sun, only rocky material could withstand the heat when the solar system was young. For this reason, the first four planets – Mercury, Venus, Earth, and Mars – are terrestrial planets.

Hubble''s New Shot of Proxima Centauri, our Nearest Neighbor

Shining brightly in this Hubble image is our closest stellar neighbor: Proxima Centauri. Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible []

Planet Sizes and Locations in Our Solar System

Mercury is the smallest planet in our solar system. Mercury is a little more than one-third the width of Earth, and has an equatorial diameter of about 3,032 miles (4,880 kilometers). Mercury is the closest planet to the Sun, orbiting at an average distance of 36 million miles (58 million kilometers).

Our Solar System

Our solar system is made up of a star—the Sun—eight planets, 146 moons, a bunch of comets, asteroids and space rocks, ice, and several dwarf planets, such as Pluto. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Mercury is closest to the Sun. Neptune is the farthest.

Our Nearest Neighbors — Google Arts & Culture

Proxima Centauri is the closest sun outside our Solar System. It''s also a very small sun, just a little larger than Jupiter. Some debate still exists over whether Proxima Centauri is actually part of the Alpha Centauri system or is passing through the system. Planets.

50 closest star systems to earth and what we might find there

A yellow, sun-like star relatively close to the solar system, Tau Ceti is in the belly of the whale constellation, Cetus. Tau Ceti has tempted astronomers looking for habitable exoplanets. This is because, as Harvard astrophysicist Avi Loeb has said, it is the closest sun-like star to the solar system. Four planets orbit the star: Tau Ceti g
