Nebular theory (10 things! I know it’s a lot baby but you got it I love you keep going)
- Each planet is isolated
- Orbits of planets are circular
- Orbits of planets tilted
- Direction of planets orbit same as rotation of sun
- Direction planets rotate on axis is same direction as sun
- Moons must rotate in same direction as planet
- Inner planets (small rocky)different from outer planets(gas giants)
- Asteroids range of properties of inner and outer
- Other things outside Kuiper belt
- Globe like structure that surrounds entire solar system made of fragments of ICE
Mercury named after
Message good for its fast speed around sun
Mercury’s atmosphere

Atmosphere comes and goes
Made of hydrogen and helium
Temp of 100 to 700 k

88 days to revolve around sun
59 days to rotate on axis
How long is Mercurys solar day?
2 mercurial years
3
