In some years, the month of February has 29 days instead of 28 days. Why is it necessary to sometimes add a day to the calendar?

• The speed at which Earth orbits the Sun varies.

• It takes the Moon about 27 days to revolve around Earth.

• It takes Earth about 365.24 days to revolve around the Sun.

• The Moon can complete more than one full cycle in some months.

Kepler's first law states that:

• The planets orbit their stars in the shape of an ellipse.

• Gravity attracts things to one another.

• Planets move faster the closer they are to the Sun.

• Perihelion is the point where a planet is farthest away from the Sun.
