Explanation:
In this sharp snapshot,
the Solar System's
largest moon Ganymede poses next to Jupiter,
the largest planet.
Captured on March 10 with a small telescope from
our fair planet Earth, the scene also includes Jupiter's
Great Red Spot, the Solar System's largest storm.
In fact,
Ganymede is about 5,260 kilometers in diameter.
That beats out
all three of its other fellow Galilean
satellites,
along with
Saturn's Moon Titan at 5,150 kilometers and Earth's own Moon at
3,480 kilometers.
Though its been
shrinking
lately, the Great Red Spot's diameter is
still around 16,500 kilometers.
Jupiter, the Solar System's ruling gas giant, is about
143,000 kilometers in
diameter
at its equator.
That's nearly 10 percent the diameter of the Sun.
