Cheers to another week! Here are your Monday Fun Facts to read and share!
55 CANCRI e is a girl’s best friend.
“[Planet] 55 Cancri e…lies about 40 light-years from Earth in the constellation of Cancer.” “…[It] was discovered in 2004 around a nearby star in our Milky Way galaxy. After estimating the planet’s mass and radius, and studying its host star’s composition, scientists now say the rocky world is composed mainly of carbon (in the form of diamond and graphite)…”
About a third of the planet’s mass is likely pure diamond!
“The Sun is the largest object in our solar system, comprising 99.8% of the system’s mass.” Its mass is around 330,000 times that of Earth.
Spacecraft have visited every planet in the Milky Way
“Spacecraft managed by JPL (Jet Propulsion Laboratory) for NASA have visited every planet in our solar system. This daunting accomplishment began when the JPL-built Mariner 2 spacecraft flew past Venus in 1962. Since then, many NASA space missions have explored the other planets [including two dwarf planets, Pluto and Ceres] and some of their many moons, as well as asteroids and comets.”
Mercury: Hot & Cold
“…The sunny side [of Mercury] may reach temperatures of 750 to 800 degrees F, while the nighttime temperature plummets to nearly -330 degrees F. The average temperature on Mercury is a balmy 354 degrees F. In addition, since Mercury has virtually no atmosphere to scatter light, its sky would be black.”
Have a great week, and stay tuned for next Monday’s five!
