The apparent diameters of both the sun and the moon, as seen from the earth, vary periodically. Because of the differing nature of their orbits, they do so in quite a different pattern/cycle. Yet calculations show that their average apparent diameter is identical, to a high degree of ...

Ancient cultures often modified natural rock formations or built stone monuments to mark the motions of the sun and moon, charting the seasons, creating calendars and monitoring eclipses. Many believed the sun revolved around the Earth, with the ancient Greek scholar Ptolemy formalizing this "geocen...
1. The Sun and the Moon The sun and the moon look near enough identical in size in Earth’s sky, as the sun is 400x bigger than the moon but 400x further away from our planet’s satellite. 2. Earth’s Satellites Earth satellites must complete an orbit of the planet within seven mo...
The radius of the Sun,R☉, is 109 times that ofEarth, but its distance from Earth is 215R☉, so it subtends an angle of only1/2° in the sky, roughly the same as that of theMoon. By comparison,Proxima Centauri, the next closeststarto Earth, is 250,000 times farther away, and...
(By comparison, the moon is roughly -14, The lower an object's magnitude, the brighter it appears to the eye.) Up close, NASA says the color of Venus is "rusty", but not the kind of deep red rust one would find on the planet Mars. Rather, pictures NASA and others have sent ...
A total solar eclipse, when the moon blocks out the Sun, happens once every 18 months. But, it will usually only appear in certain places on Earth. As I mentioned earlier, the actual color of the Sun is white, although it can look to us like it is yellow, orange or even shades of...
Earth is intimately tied to the star around which it revolves, the Sun, and the satellite that revolves around Earth itself, the Moon. Without the Sun, of course, life on Earth simply could not exist, not just because of the need for light but to an even greater degree because of the...
