3. Mnemonic:
My Very English Mum Just Sum Up Net Profit
5. Define:
- Asteroid: a small rocky body that drifts around the solar system
- Meteorite: an asteroid on a collision course with another planet
- Comet: mixture of rock and ice in very elliptical orbits around the sun
- Stellar Cluster: group of stars that are physically close to each other in space, created by the collapse of the same gas cloud
- Constellation: patterns of stars that are not particularly close to each other
- Light year: 1 light year is defined as the distance light travel in one year
6. Compare distances between stars and between galaxies
Describe motion of constellation over:
1. 1 night: The various constellation and stars are not the same as every night. This is because on any night, the stars constellations ‘rises’ about 4 minutes earlier than on the previous night. For example, the night sky at 10 pm on February 14 will be the same as at 9.54 p.m on February 15th.
2. 1 year:
