The Planets and the Solar System.
Planets 2.
" A planet is a celestial body that revolves around a.
central star and does not shine by its own light " (Grolier,.
1992). The only planetary system that is known to man is our.
solar system. It is made up of nine planets which range in size.
and make-up. The nine major planets in our solar system are.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and.
Pluto. There are also many other minor planets which are also in.
our solar system, but they are unimportant compared to the nine.
major planets. In this paper I will discuss the planets and how.
they are each unique.
Mercury which is the planet that is closest to the sun is.
the first planet I will discuss. Mercury is the smallest of the.
inner planets. It is speculated that the heat from the sun made.
it impossible for the gases present to become part of the.
planetary formation. The surface of Mercury is extremely hot. .
It is approximately 470 degrees celsius on the surface and is.
thought to be even hotter at the two " hot spots." These " hot.
spots " are on opposite ends of the equator. It is the heat of.
the surface that makes it impossible for Mercury to have any type.
of atmosphere.
Mercury orbits the sun once every 88 days and has a true.
rotation period of 58.6 days. " It is the closest planet to the.
sun and therefore orbits faster than any other planet ".
(Thompson/Turk, 542, 1993). It is said that Mercury rotates.
three times for every two trips around the sun, so that during .

every alternate perihelon passage the same face points directly.
at the sun. " Geologically, the most remarkable features of.
Mercury are compressional cliffs or faults, just the sort of.
wrinkles that might form in the crust if the interior of the.
planet shrank slightly " (Morrison, 74, 1993).
Planet Earth by P. ... It has to be spread out, the skin of this planet. ... It has to be made bright, the skin of this planet till it shines in the sun like gold leaf. ...

The Planets A planet is a celestial body that revolves around a central star and does not shine by its own light. ... Mercury, which is the planet that is closest to the sun, is the first planet I will discuss. ... Since it is the closest planet to the sun it orbits faster than any other planet. ...

Inner Planets Mercury It is the planet closest to the sun. ... It is the second smallest planet. ... This planet has no moon. ... Venus is Earth's sister planet. ... It is the only known planet to contain life, even though other planets have atmospheres and water. ...
Murray believes he has a good reason to believe that there is a tenth planet. ... One could be planet X. ... Planet X is too faint to find even with the UK Schmidt Telescope. ... He then thought he hadn't found the right planet. ... Whitmire and Matese have no plans for a targeted search for Planet X. ...
Extrasolar Planets The universe is composed of many galaxies, planets, an abundant amount of stars, and matter. ... An extrasolar planet is a planet around other stars, and these planets are Mercury, Venus, Earth and Mars. One can see these planets through powerful telescopes. ... An observed Doppler-shift could be produced either by a low mass planet or by a bigger planet. ... There are many elliptical orbits than circular orbits of planets in the solar system, and also most of these planets are bigger than Jupiter. ...
The study of space weather and weather on other planets provides scientists with information that provides a greater knowledge of how our planet works. ... These factors cause the planet's weather system to be erratic. ... Mars, also known as the "Red Planet", is very cold and dry. ... Seasons Seasons on any planet are created by the combination of 2 factors: axial tilt and the planet's distance from the Sun (Caplinger). ... This can cause the temperature to drop about 50*F and affect the planet's heat balance, seasons, and occurrence of water vapor clouds ("Exploring the Plane...
