This week we’ve been reading about the diversity and excitement in our Solar System. For this post,
watch this ten minute youtube video which gives an over view of our solar system. There are several
inaccuracies within the clip. Find them and report back to your fellow students.
Can you find alternative video clips that do a better job of explaining this topic?
Note that in order to complete this week's Discussion Board assignment you must write a minimum of
three posts: a response of your own and replies to two of your classmates.

The video, “The Solar System: A Brief Glance”, discussed several inaccuracies of our solar
system. The first inaccuracy I noticed was that it stated that the solar system formed 5 billion
years ago instead of 4.6 billion. The video states that Jupiter has 63 moons when it actually has
79, and Saturn has 47 when it actually has 82. The YouTube video, “101 Facts About the Solar
System”, is not only more accurate but also up to date given that this video was made in 2020. It
also offers more information about our Solar System.

Using the latest information from the recent MESSENGER mission to Mercury and the Lunar
Reconnaissance Orbiter (LRO) to the moon, discuss how finding water ice has affected our perception of
these two celestial objects.
The information from the Recent Messenger mission to Mercury states that "Mercury is hot—really hot. Its
surface temperature at the equator can rise to over 400 C. Yet Earth-based radar shows evidence for
water ice at Mercury's poles." Since Mercury is the closest planet to the Sun, we assumed that it wouldn't
be possible to inhabit, let alone ice water, because of the high temperatures of heat it experiences. Before
the findings of water ice on the Moon, we assumed that Moon was completely dry due to the heat of
impacts from giant objects that hit Earth billions of years ago, the evaporation of any water that could
have been there.
