MEANING |
| Barnard, Edward Emerson |

astonomer. Discovered
Jupiter's moon Amalthea and the fourth nearest star to Earth, known as
Barnard's Star (see below). Lived from 1857 - 1923. |
| Barnard's Star |
Fourth nearest star to Earth. 5.9 light years away. |

80km in diameter, 10th moon is distance from Uranus. |

| 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. |
