Explanation: Meteoroids. These small objects often plunge through the Earth's atmosphere and heat with friction until they vaporize. These are commonly known as "shooting stars". A meteoroid that can survive its flight through the Earth's atmosphere and land on the ground is called a _____________. Explanation: Meteorite. Many of these meteorites can be seen in museums. The largest known meteorites have masses of about fifty tons and a chemical analysis reveals them to be formed of the same elements that exist on Earth. ________________ dust and gas is a sparse distribution of micrometeorites and atoms or electrons of gas throughout the solar system. Explanation: Interplanetary. Individual particles have been detected as they strike rockets and collectively, the particles can be observed by the sunlight they reflect. Evidence of interplanetary gas also comes from space probes whose instruments have recorded rapidly moving atoms and charged atomic particles. ____________ is the planet nearest to the sun and has the shortest period of revolution about the sun, 88 of our days. Explanation: Mercury. Mercury is the smallest of the planets and has a diameter of only about 3,000 miles. The lighted side of Mercury has a temperature of about 610° K (640° F), hot enough to melt tin and lead. The dark side of the planet is too cold to radiate a measurable amount of heat. Named for the goddess of love and beauty, _________ is sometimes called the "Earth's sister", for it is most like the Earth in mass and size of all the planets. Explanation: Venus. Mercury and Venus are the only planets in our solar system that have neither rings nor moons. ________ is sometimes called the "newspaper planet" as it is the most favorably situated of the planets for observation from the Earth. Explanation: Mars. Mars has a thin atmosphere which is composed almost entirely of carbon dioxide (95%). The surface of Mars has many signs that the planet may once have had an abundance of water, which would indicate that at one time it had a much thicker atmospher. Due to the thinness of its atmosphere today, any water on the surface would instantly vaporize.

Below is a size comparison of the four closest planets. From left to right, Mercury, Venus, Earth, and Mars: Named for the leader of the gods, ___________ is the largest and most massive object in the solar system next to the sun. Explanation: Jupiter. Jupiter has 63 known satellites. Below is an image showing an approximate size comparison of Jupiter and Earth: The unique ring around __________ makes this planet one of the most impressive telescopic objects. Explanation: Saturn. Saturn is the second largest planet. It is named for the god of seed sowing, the father of Jupiter. Saturn has sixty known satellites.

Galileo first saw the rings of Saturn, but was unable to discern them clearly with his crude telescopes. In 1655, Huygens was able to describe their true form. The rings have the appearance of the brim of a straw hat surrounding the planet at its equatorial plane. Below is an image of Saturn as captured by the Hubble Space Telescope in October of 1996:
