Astronomical unit

Many of us, while still in grade school, learned about the staggering distances to planets, stars and galaxies. The sun is approximately 150 million km or 93 million miles away, a distance that is known as the "astronomical unit" (AU). Venus, our closest neighbor, is 0.72 AU from the sun, while Mars is 1.52 AU from the sun. Neptune, the most distant planet, is 30 AU from the sun (i.e., 44.8 billion km or 27.9 billion miles). The Voyager 2 spacecraft, launched in 1977, reached Jupiter just two…

Kepler’s Laws, Kepler is credited with 3 laws regarding the movement of celestial bodies orbiting other celestial bodies. Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky. Kepler's 1st Law: The Law of Orbits, Kepler's 2nd Law: The Law of Areas, and Kepler’s 3rd Law: The Law of Periods. Kepler's laws were derived for orbits around the sun, but they apply to…

industry (Not For Sale). While sex trafficking is the most well known form of slavery, labor trafficking is the most common. Laborers are sold for an average of $4,000 each and are indebted to their owners for the rest of their lives (Not For Sale).

The Kepler Telescope main instrument is a photometer. This instrument measures the brightness of stars within its field of view. Data is then gathered and analyzed to detect any variations or deviations of light which is caused by the transits of plants of host stars. These dips in light help in detecting planets in "Habitable Zones". Gliese-581g The planet Gliese 581g is one of six possible planets in the constellation Libra. This exoplanet was discovered in late September 2010. The main reason…
