Space Summary Seasons: A year: Day & night: Inner Planets: Earth is tilted on its axis. When The Earth moves The Earth the Northern hemisphere is around the Sun. This is spins on its Mercury, Venus, Earth, Mars. tilted towards the Sun, we have called an orbit and it axis anti They are small and mostly solid. summer. We are nearer the takes 365.25 days (0.25 clockwise. This Outer Planets: Sun- the days are longer and x 4 = a leap year where takes 24 hours.

Planets: Weight Mercury Weight is a force that acts on an object due to the pull of Moon & tides: Venus gravity on its mass and it is measured in newtons (N). It takes 29.5 days for the Moon to Weight = Mass (kg) x gravitational field strength (N/kg) Earth orbit the Earth.
