Explanation:
After just passing Mercury, the robot spacecraft Mariner 10 looked back.
The
above picture is what it saw.
Mercury,
the closest planet to the
Sun, is heavily cratered much like
Earth's Moon.
As Mercury slowly rotates, its surface
temperature varies from an unbearably cold -180 degrees
Celsius in the half facing away from the Sun,
to an unbearably hot 400 degrees
Celsius
in the half facing toward the Sun.
Mercury is slightly larger than
Earth's Moon and much
denser.
The Mariner 10 spacecraft swooped by
Mercury three times in its journey around the inner
Solar System in the mid-1970s.
This outbound view has similarities to the
inbound view.
Nearly half of
Mercury's surface
has yet to be photographed in detail.
