Mass = Gravity
Gravity is the force that holds the solar
system together.
The mass (and thus gravity) of the Sun
keeps all the planets orbiting around it.
The mass (and thus gravity) of the Earth
keeps the Moon orbiting around it.

The Moon has
much greater affect
on the Earth’s tides
because it is closer
to the Earth.
When the Moon,
Sun, and Earth are
aligned (new and
full Moon), the tides
are the greatest
(Spring Tide)

Seasons are caused by the Earth’s
revolution and tilt. In the Northern
Hemisphere, we are actually closer to
the Sun in winter, but our tilt is away
from the Sun, so we don’t have direct
sunlight. In the summer, even though
we are further from the Sun, we receive
direct sunlight for the majority of the
day, causing it to be warmer.
