Learn how far the Sun is from Earth in different units, how long it takes to get there, and how Earth is moving away from the Sun. Find out how to measure the distance to the Sun and why it matters for space exploration.
21 sty 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.
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). The AU is used to measure longer distances in the solar system.
21 lut 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.
From Earth, it is 1 astronomical unit (1.496 × 108 km) or about 8 light-minutes away. Its diameter is about 1,391,400 km (864,600 mi), 109 times that of Earth. Its mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System.
The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.
