The Earth's and Moon's rotation.
cuz The moon's apparent "shape" changes because as it orbits the Earth, the light from the sun hits it at different angles causing observers on Earth to see "different shaped moons". The moon really is always a sphere.
the moons cycle i think
it is called the phases of the moon
The moons gravational pull in the earth
You would need a telescope to see the moons of Mars, Phobos and Diemos, since their apparent magnitudes are +11.3 and +12.4 respectively. But with a good telescope and good conditions you can see them from Earth.
rays of light from the sun
Negative numbers are brighter. Our Sun has an apparent magnitude of -26.73, the Moon around -12. Sirius on the other hand has an apparent magnitude of -1.46, whereas apparent magnitude of Pluto's smallest moons Hydra and Nix is 23.
The moons gravitational pull and how the sun tilts
The moons gravitational pull is what causes tides.
Uranus has at least 27 moons. It is the seventh planet from the Sun and is known for its tilting axis which causes extreme seasons.
Spring tides are caused by new and full moons. Neap tides are caused by 1st and 3rd quarter moons.
