MERCURY Mercury takes 59 days to make a rotation but only 88 days to circle the
Sun. That means that there are fewer than 2 days in a year!
Many astronomers believe that Mercury might be the core of what was once a
much larger planet -- it appears to be a huge ball of iron covered by a thin layer
of rock.
Venus is the brightest planet in our sky and can sometimes be seen with the
naked eye if you know where to look. It is the solar system's brightest planet --
yellow clouds of sulfuric acid reflect the sun's light.
Mars is the home of "Olympus Mons", the largest volcano found in the solar
system. It stands about 27 kilometers high with a crater 81 kilometers wide.
Jupiter is the largest planet the solar system, but it spins very quickly
on its axis. A day on Jupiter lasts only 9 hours and 55 minutes. I get dizzy
just thinking about it!

Jupiter is so big that you could fit all the other planets in the solar system
inside it.
The red spot of Jupiter is the biggest, most violent storm in the known
universe -- that spot is at least three times the size of earth!
