Earth’s Distance from the Sun
The average distance between the Earth and the Sun is known as an Astronomical Unit (AU).
It is approximately 149.6 million kilometers (about 93 million miles).
This distance varies slightly throughout the year because Earth’s orbit is elliptical—closest at perihelion (~147.1 million km) and farthest at aphelion (~152.1 million km).
The astronomical unit is a fundamental standard for measuring distances within our solar system.
Key facts:
Average distance ≈ 149.6 million km (1 AU)
Varies due to elliptical orbit
Basis for measuring planetary distances
Understanding Earth’s distance from the Sun is essential for studying seasons, climate, and orbital mechanics.
Petameter
A petameter (Pm) is a unit of length in the metric system, equal to 1 quadrillion meters (1 petameter = 10¹⁵ meters). This unit is extremely large and is used mainly in astronomy and theoretical physics to describe vast distances, such as those between stars or galaxies. For example, one petameter is about 105.7 light years. Since it measures such enormous distances, the petameter is not used in everyday life or common scientific applications—it’s mostly used in discussions about the scale of the universe.
