Lesson#2:
Jupiter is the fifth planet from the Sun and the largest planet in the solar system, it is also the fourth brightest object in the sky. Due to its prominence in the sky, the Romans named the planet for their chief god, Jupiter. Jupiter’s year, or the time it takes to complete an orbit about the Sun is 11.9 Earth years. One day on Jupiter or the time it takes to rotate on its axis, is about 9.9 hours, less than half on Earth day. Unlike the rocky inner planets of the solar system such as Mercury, Venus, Earth, and Mars, Jupiter is a ball of dense gas and has no solid surface. Jupiter’s most famous storm, the Great Red Spot, has been going on for centuries. It is so enormous that if three Earths were placed side by side in front of it, they would scarcely cover it. The earliest report of a red spot was by Robert Hooke in 1664. The cause of the Great Red Spot is not yet known, but its motion is such that it must sustain itself on energy gained from the upper atmosphere. Jupiter is encircled by at least 61 satellites and a series of thin rings and is similar to a miniature solar system.

Lesson#1:
Mars is the fourth planet from the Sun. Mars is named for the Roman god of war and is sometimes called the red planet because it appears fiery red in Earth’s night sky. An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism. The name of the month March derives from Mars. Mars is a relatively small planet, with about half the diameter of Earth and about one-tenth Earth’s mass. Mars is believed to be about the same age as Earth, having formed from the same spinning, condensing cloud of gas and dust that formed the Sun and the other planets about 4.6 billion years ago.
The Martian day - that is, the time it takes Mars to rotate once on its axis—is about a half an hour longer than an Earth day and is sometimes called a sol. Its year, or the time it takes to revolve once around the Sun, is about two Earth years long. Mars has two moons, Phobos and Deimos, which are named after the dogs of the Roman god Mars. These tiny bodies are heavily cratered dark chunks of rock and may be asteroids captured by the gravitational pull of Mars. Phobos orbits Mars once in less than one Martian day, so it appears to rise in the west and set in the east, usually twice each day. Deimos has the more ordinary habit of rising in the east and setting in the west.
