Kepler is studying over 150,000 stars in our neighborhood of our galaxy in the Cygnus and Lyra constellations.
Stars create their energy through the process of nuclear fusion. Fusion is the process in which light atoms combine to form heavier atoms, giving off excess energy in the process.

A 'planet' is defined as a round celestial body that is in orbit around the sun.

Kepler’s 1st Law

Angular Parameters of Elliptical OrbitCC BY-SA 3.0
Orbits are elliptical.
Kepler’s 2nd Law
The line connecting the Sun to a planet sweeps equal areas in equal time.

Kepler’s 3rd Law
Kepler's third law, the law of periods, relates the time required for a planet to make one complete trip around the Sun to its mean distance from the Sun. "For any planet, the square of its period of revolution is directly proportional to the cube of its mean distance from the Sun." Applied to Earth satellites, Kepler's third law explains that the farther a satellite is from the Earth, the longer it will take to complete an orbit, the greater the distance it will travel to complete an orbit, and the slower its average speed will be

The main point of Kepler’s third law is to measure distances between planets
Earth’s gravity pulls on the moon and keeps it in orbit around the Earth.

What is the difference between rotation and revolution?
Rotation = earth’s spinRevolution = Orbit around the sun

Because it takes the Earth 365.25 days to orbit the sun, we end up with one extra day every 4 years. So the year with the extra day is called leap year.

The sun warms the earth differently according to Tilt of the Earth.This change in the tilt of the earth is what causes the seasons.
The precession causes the vernal equinox point g to migrate clockwise along the Earth's orbit, shifting the Earth�s seasons relative to the orbit's eccentric shape; this motion constitutes the "precession of the equinoxes." The angle v between g and P is the moving longitude of perihelion and is used in the precession index esinv to track Earth-Sun distance.

Precession is the change in direction of the axis, but without any change in the tilt. This changes the relative positions of the stars but does not affect the seasons.

Nutation is a wobbling around the precessional axis. Does is affect the seasons?

As seen from above, a large planet orbits a star–or rather the star and planet orbit their shared center of mass, or barycenter.
The gravity of the moon pulls on the ocean’s water. This causes tides.
Scijinks :: Tidal weirdnessscijinks.nasa.gov500 × 284Search by imageDrawing shows Moon's gravity pulling about 45 degrees from pull of sun's gravity. Their combined pull is greatest at a point between, thus creating the highest tide there, rather than when the Moon is directly overhead.
Both the pull of gravity from the sun and the moon cause tides.

The Moon in turn induces tides on Earth - both ocean and solid Earth tides. These tides vary on a 12-hour interval basis.
There is a bulge at the equator of the Earth because the circumference around the equator is slightly bigger than the circumference around the poles.
