List of nearest exoplanets

The first report of an exoplanet within this range was in 1998 for a planet orbiting around Gliese 876 (15.3 light-years (ly) away), and the latest as of 2024 is one around GJ 1289 (27.3 ly). The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away.

What are the four closest planets to the Sun?

Terrestrial planets include the four closest planets to the Sun located between the Sun and the asteroid belt; Mercury, Venus, Earth, and Mars.

[14] Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc).. α Centauri A and B are Sun-like stars (class G and K

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.

Mercury is the closest planet to the Sun, with surface temperatures of up to 430°C (800°F), but Venus is still hotter. Like the Moon, Mercury has water ice in craters at its poles that almost

Mercury, world of extremes | The Planetary Society

Mercury is the smallest planet in the Solar System and the closest one to the Sun. It''s also a little-explored world, full of mystery, with a surface split into extremes and an interior that puzzles scientists. Mercury is only slightly larger than Earth''s Moon.

Why is Mercury the closest planet to Earth?

This large range arises from the planet''s high orbital eccentricity. 26 Essentially, because Mercury is closest to the Sun, when taking an average over time, Mercury is most often the closest planet to the Earth, 120 121 and—in that measure—it is the closest planet to each of the other planets in the Solar System. 122 123 124 b

Mercury Facts | Information, History, Location, Size & Definition

Mercury is the closest planet to the Sun but, perhaps surprisingly, it does not have the highest temperatures. It is the second densest planet of the Solar System, but also the smallest planet.The structure of Mercury makes it the most similar planet to Earth.

Which planet is ''closest to Earth'' when averaged over time?

For example, essentially because Mercury is closer to the Sun than Venus, Mercury spends more time in proximity to Earth; it could, therefore, be said that Mercury is the planet that is "closest to Earth when averaged over time".

Mercury Facts

Mercury is the closest planet to the Sun. Your weight on Mercury would be 38% of your weight on Earth. Mercury is the smallest planet in the Solar System. One of five planets visible with the naked eye a, Mercury is just 4,879 Kilometres across its equator, compared with 12,742 Kilometres for the Earth.

Mercury has the most eccentric orbit of all the planets in the Solar System; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 mi). It takes 87.969 Earth days to complete an orbit. The diagram illustrates the effects of the eccentricity, showing Mercury''s orbit overlaid with a circular orbit having the same semi-major axis.

In Depth | Mercury – NASA Solar System Exploration

The smallest planet in our solar system and nearest to the Sun, Mercury is only slightly larger than Earth''s Moon. Mercury formed about 4.5 billion years ago when gravity pulled swirling gas and dust together to form this small planet nearest the Sun. Like its fellow terrestrial planets, Mercury has a central core, a rocky mantle, and a

Mercury Facts

Despite its proximity to the Sun, Mercury is not the hottest planet in our solar system – that title belongs to nearby Venus, thanks to its dense atmosphere. But Mercury is the fastest planet, zipping around the Sun every

Distance Between Planets Of The Solar System | KM & Current

The main reason for the planets to vary their distance is due to elliptical orbits. No planet in our Solar System orbits the sun in a perfect circle which means that the distance between planets is never the same. For this reason, to calculate the distance, we use the average to measure how far planets are from one another.
