The Planets plus the Dwarf Planet Pluto Our solar system consists of the sun, eight planets, moons, many dwarf planets or plutoids, an asteroid belt, comets, meteors, and others. The sun is the center of our solar system the planets, their moons, a belt of asteroids, comets, and other rocks and gas orbit the sun. The eight planets that orbit the sun are in order from the sun Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune. Another large body is Pluto, now classified as a dwarf planet or plutoid. A belt of asteroids minor planets made of rock and metal lies between Mars and Jupiter. Nd Arc 4Th Report Pdf' title='2Nd Arc 4Th Report Pdf' />These objects all orbit the sun in roughly circular orbits that lie in the same plane, the ecliptic Pluto is an exception it has an elliptical orbit tilted over 1. Easy ways to remember the order of the planets plus Pluto are the mnemonics My Very Excellent Mother Just Sent Us Nine Pizzas and My Very Easy Method Just Simplifies Us Naming Planets The first letter of each of these words represents a planet in the correct order. The largest planet is Jupiter. It is followed by Saturn, Uranus, Neptune, Earth, Venus, Mars, Mercury, and finally, tiny Pluto the largest of the dwarf planets. Jupiter is so big that all the other planets could fit inside it. The Inner Planets vs. Outer Planets. The inner planets those planets that orbit close to the sun are quite different from the outer planets those planets that orbit far from the sun. The inner planets are Mercury, Venus, Earth, and Mars. They are relatively small, composed mostly of rock, and have few or no moons. The outer planets include Jupiter, Saturn, Uranus, Neptune, and Pluto a dwarf planet. They are mostly huge, mostly gaseous, ringed, and have many moons again, the exception is Pluto, the dwarf planet, which is small, rocky, and has four moons. Temperatures on the Planets. Generally, the farther from the Sun, the cooler the planet. Differences occur when the greenhouse effect warms a planet like Venus surrounded by a thick atmosphere. Density of the Planets The outer, gaseous planets are much less dense than the inner, rocky planets. The Earth is the densest planet. Saturn is the least dense planet it would float on water. The Mass of the Planets. Jupiter is by far the most massive planet Saturn trails it. Uranus, Neptune, Earth, Venus, Mars, and Pluto are orders of magnitude less massive.

The planet with the strongest gravitational attraction at its surface is Jupiter. Although Saturn, Uranus, and Neptune are also very massive planets, their gravitational forces are about the same as Earth.

Projects List mainly include abstract,report in pdf, project presentation,project. This is full text of the report of Satish Chandra Committee 1989, 692 pages in original. This may not be fully legible due to an error in the old copy of the. This is because the gravitational force a planet exerts upon an object at the planets surface is proportional to its mass and to the inverse of the planets radius squared. A Day on Each of the Planets. A day is the length of time that it takes a planet to rotate on its axis 3. A day on Earth takes almost 2. The planet with the longest day is Venus a day on Venus takes 2. Earth days. A day on Venus is longer than its year a year on Venus takes only 2. Earth days. The planet with the shortest day is Jupiter a day on Jupiter only takes 9. Earth hours When you observe Jupiter from Earth, you can see some of its features change. The Average Orbital Speed of the Planets. As the planets orbit the Sun, they travel at different speeds. Each planet speeds up when it is nearer the Sun and travels more slowly when it is far from the Sun this is Keplers Second Law of Planetary Motion. The Planets in Our Solar System.

TemperatureKRange or AverageNumber of Moons. Another Planet In 2. Pluto was observed in the Kuiper belt. A few astronomers think that there might be another planet or companion star orbiting the Sun far beyond the orbit of Pluto. This distant planetcompanion star may or may not exist. The hypothesized origin of this hypothetical object is that a celestial object, perhaps a hard to detect cool, brown dwarf star called Nemesis, was captured by the Suns gravitational field. This planet is hypothesized to exist because of the unexplained clumping of some long period comets orbits. The orbits of these far reaching comets seem to be affected by the gravitational pull of a distant, Sun orbiting object. Planet Activities and Quizzes. Planet Coloring pages.
