Billion The American version of billion is one thousand million and is written as 1,000,000,000. The English version is one million million and is written 1,000,000,000,000. Scientists generally use the American version, or to avoid confusion, don't use billion at all and keep to scientific notation.
Black Hole The core of a collapsed star. Its gravity is so strong that not even light can escape.
Bode, Johann Elert German astronomer, mostly known for "Bode's Law" (see below). Lived from 1747 to 1826.
Bode's Law A mathematical formula designed by Bode to generate the orbits of objects orbiting the Sun in A.U. Although it appears to be accurate for the planets (including the asteroid belt) up to Uranus (it actually predicted Uranus' orbit before it was discovered), it seems to go wrong after that and misses out Neptune. The law appears to back-up theories about how Solar Systems are formed (the distances between planets roughly doubles the further you move out of the Solar System) and it is more coincidental that the positions of objects up to Uranus fit in with Bode's Law.
