Teach Astronomy - Orbit Eccentricity

http://www.teachastronomy.com/ Orbital eccentricity is the amount by which an orbit deviates from a circle. Mathematically it's defined as the distance between the two foci of an elliptical orbit divided by the major axis. A circle has an ellipticity, denoted by the little symbol "e", of

Teach Astronomy - Pluto

http://www.teachastronomy.com/ Pluto is the outer sentinel of the solar system. With a size of only 2,300 kilometers, it is half the size of Mercury and two-thirds the size of Earth's moon. Its mean distance from the sun is 39 astronomical units, but it has a highly eccentric orbit with

How Far Is Earth From the Sun?

It's amazing to think that for the majority of human history, we had almost no understanding about the Sun. We didn't know what it was made of, how it formed, or how it produced energy. We didn't know how big it was, and we didn't know how far away it was. We orbit the Sun at a distan

Our Sun is located 24-26,000 light years from the center of the Milky Way. It circles the galaxy every 225-250,000 years, at a speed of 220 kilometers per second. The sun is a medium size star, a Yellow Dwarf, G type main sequence. It’s about one million times the size of planet Earth.

Teach Astronomy - Astronomical Units

http://www.teachastronomy.com/ The astronomical unit is defined as the mean distance between the Earth and the Sun. It has to be defined as the mean because the orbit is elliptical by a couple of percent. The astronomical unit is 150 million kilometers or 98 million miles. This sets the
