Learn how far the Sun is from Earth in different units, how long it takes to reach it, and how Earth is moving away from the Sun. Find out how to get to the Sun in a car or a spacecraft, and what will happen when the Sun becomes a red giant.
In actuality, the Sun distance to Earth varies around 3% as the earth orbits the sun. Usually, the earth-to-sun distance is known as one Astronomical Unit (1 AU) which is around 149.598 million kilometers (92.956 million miles).
21 Φεβ 2019 · The average distance between the Earth and the Sun is 92,955,807 miles (149,597,870 km). Most people just round it up to 93 million miles. This distance is called an astronomical unit or AU and is used to measure and compare other distances in space.
21 Ιαν 2022 · Earth's distance from the sun averages about 93 million miles (150 million km), which scientists also call one astronomical unit (1 AU).
The Sun is about 93 million miles (150 million kilometers) from Earth. Its nearest stellar neighbor is the Alpha Centauri triple star system: red dwarf star Proxima Centauri is 4.24 light-years away, and Alpha Centauri A and B – two sunlike stars orbiting each other – are 4.37 light-years away.
Historically, the astronomical unit was conceived as the average Earth-Sun distance (the average of Earth's aphelion and perihelion), before its modern redefinition in 2012. The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
2 Αυγ 2017 · The Earth is 149.6 million kilometers from the Sun on average, but it varies between 91.4 and 94.5 million kilometers due to the elliptical orbit. Learn how ancient and modern methods have estimated the distance between the Sun and the Earth.
