# Find Earth angular momentum

Find Earth angular momentum using Earth-Sun distance and mass of Earth?
Earth - Sun distance 149.6x109 m
Mass of the Earth 5.9742x1024 kg

Earth angular momentum

For an orbit, angular momentum is conserved, and this leads to one of Kepler's laws. For a circular orbit, angular momentum is

The average angular momentum is mvr, treating the Earth as if it were a point mass.

Mean distance from Earth to Sun is 149.6×106 km (8.31 minutes at the speed of light)
Mass of the Earth is 5.9742×1024 kg

Earth takes 365 days to go one complete circle around Sun.

Average angular momentum

Earth angular momentum is 2.663x1040 kgm2s-1

There is no special name for this combination of units. The direction of the vector is perpendicular to the orbit.
