Mercury

What is Mercury?
• Mercury is the first planet from
the Sun and the smallest planet in
the Solar System. It is a terrestrial
planet with a heavily cratered surface
due to the planet having no geological
activity and an extremely tenuous
atmosphere (called an exosphere).
How was Mercury
discovered?
• 1631: Thomas Harriott and Galileo
Galilei observe Mercury with the newly
invented telescope. 1631: Pierre
Gassendi uses a telescope to watch
from Earth as Mercury crosses the face
of the Sun.
Size
• Despite being the smallest planet in the Solar
System with a mean diameter of 4,880 km
(3,030 mi), 38% of that of Earth's, Mercury is
dense enough to have roughly the same
surface gravity as Mars. Mercury has
a dynamic magnetic field with a strength about
1% of that of Earth's and has no natural
satellites. It’s size is about 74800000 km^2
Structure
• Mercury is the second densest planet,
after Earth. It has a large metallic core
with a radius of about 1,289 miles
(2,074 kilometers), about 85 percent of
the planet's radius. There is evidence
that it is partly molten or liquid.
Seasons
• Mercury's axis of rotation is tilted just 2
degrees with respect to the plane of its
orbit around the Sun. That means it
spins nearly perfectly upright and
so does not experience seasonsas
many other planets do.
Temperature in Mercury
• Temperatures on Mars average about -
81 degrees F.However, temperatures
range from around -220 degrees F. in
the wintertime at the poles, to +70
degrees F.
