Ever since the 16th century when Nicolaus Copernicus demonstrated that the Earth revolved around in the Sun, scientists have worked tirelessly to understand the relationship in mathematical terms.

At about 864,000 miles (1.4 million kilometers) wide, the sun is 109 times wider than Earth, and it accounts for more than 99.8 percent of the solar system's total mass.

While the sun's radiation races to Earth and drives our weather, the comparatively lethargic — but still zippy, moving at a speed of over 1 million mph (1.6 million km/h) — solar ...

Called aphelion, the sun at that moment will be 94,502,939 miles (152,087,738 km) from our Earth (measured from center to center), or 3,096,946 miles (4,984,051 km) farther as compared to when the ...

Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.

While the sun's radiation races to Earth and drives our weather, the comparatively lethargic — but still zippy, moving at a speed of over 1 million mph (1.6 million km/h) — solar ...
