Earth orbit axis tilt rotation [animated pictures and text]

  • All of the planets go around
    (orbit) the Sun in an
    anti-clockwise direction
    (opposite to a clock)

  • It takes the Earth 365
    days (one year)
    to orbit
    the Sun. Can you see
    the Moon orbiting the Earth?

  • So Earth orbits (revolves
    around)
    the Sun
    but also rotates (spins)
    anti-clockwise on its axis.

  • The axis is an imaginary
    line
    through the Earth,
    shown here in yellow.

  • However, at some point in history
    it is thought that Earth was in
    collision with another
    planet called Theia.

  • This caused the Earth to
    develop a tilt of around
    23 degrees.. This animation
    shows how big that is.

  • So now the Earth rotates
    on its axis with
    a tilt of 23 degrees.

  • As the Earth orbits the Sun
    things have now changed
    .

  • However, the angle and
    direction of the tilt
    is always the same
    throughout the year.
