Astronomy Theme Target Review : 

Astronomy Theme Target Review Exam: October 19th

Astronomical Unit : 

Astronomical Unit The Astronomical Unit (AU) represents a distance of Earth's average distance to the Sun, or about 93,000,000 miles. Used to measure distances within our solar system

Light Year (not Buzz) : 

Light Year (not Buzz) A light-year is a unit of distance. Measures distances beyond our solar system. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. 1 light-year is equal to 9,500,000,000,000 kilometers. On Earth, a kilometer may be just fine. It is a few hundred kilometers from New York City to Washington, DC; it is a few thousand kilometers from California to Maine. In the universe, the kilometer is just too small to be useful. For example, the distance to the next nearest big galaxy, the Andromeda Galaxy, is 21 quintillion km. That's 21,000,000,000,000,000,000 km.

Parallax : 

Parallax To determine the distance to a star, astronomers measure the apparent change in its position over one year. As the Earth orbits the Sun during this period, the observer (taking measurements at the opposite sides of the Earth's orbit) notices an apparent movement of the star compared to more distant stars. The closer a star is to the Earth the greater the observed parallax.
