About Earth's Orbit & Sun Distance
The Sun to Earth Distance Calculator uses precise astronomical algorithms to calculate how far Earth is from the Sun on any given day. Because Earth travels in an elliptical orbit rather than a perfect circle, the distance between our planet and the Sun changes continuously throughout the year.
Key Orbital Milestones
- Perihelion (Closest Approach): Occurs in early January (around January 3–5). Earth is approximately 147.1 million kilometers (91.4 million miles) away from the Sun.
- Aphelion (Farthest Point): Occurs in early July (around July 3–5). Earth is approximately 152.1 million kilometers (94.5 million miles) away from the Sun.
- Astronomical Unit (AU): Defined as roughly the average distance between Earth and the Sun, equal to exactly 149,597,870.7 kilometers (about 93 million miles).
- Light Travel Time: Sunlight takes approximately 8 minutes and 20 seconds to travel across the distance from the Sun to Earth.
