Earth Quote by Joanne Baker
““The Sun contains most of the mass of the solar system (99.9 percent) in a ball whose diameter is about 100 times that of the Earth. It is about 150 million kilometers away, and light from it takes eight seconds to reach us.””
About This Quote
The Sun holds almost all the solar system’s mass and is far away, so its light takes several seconds to reach Earth.
In simple terms: The Sun is massive and distant, causing an eight‑second light travel time.
