6 million km 8 minutes 20 seconds Aphelion (Farthest) 152. This concept extends to the furthest reaches of space; looking at distant stars means viewing them as they were years or millennia in the past.
Calculate Your Personal Sunlight Lag Time Based on Your Location
Measuring the Cosmos Determining this precise interval was a feat of human ingenuity that required centuries of scientific advancement. Because the Earth’s orbit is elliptical rather than a perfect circle, the distance between our planet and the sun varies throughout the year.
The consistency of this travel time is a cornerstone of modern technology. Early astronomers like Ole Rømer observed the moons of Jupiter and noted discrepancies in their eclipse timings, providing the first evidence that light had a finite speed.

The sun, being the closest star, provides the most immediate and practical application of this principle, serving as a natural laboratory for understanding the physics of light and time. 1 million km 8 minutes 13 seconds Average Distance 149.
