This lesson offers an in-depth analysis of the four outer planets: Jupiter, Saturn, Uranus and Neptune. Since the beginning of time, humans have been fascinated by the planets in outer space. There are four inner planets which are relatively smaller and also known as “terrestrial planets” – Mercury, Venus, Earth, and Mars. Outer planets are significantly bigger than the inner planets as Jupiter is measured to be 88846 miles in diameter and Mercury is measured to be 3031 miles in diameter. The giant planets have pronounced magnetospheres produced by the combination of their rapid rotations and strong magnetic fields. Earth is the third planet from the sun and is the largest of the terrestrial planets. Pluto: Once considered a planet, Pluto has been classified as a dwarf planet since 2006. The Nine Planets has been online since 1994 and was one of the first multimedia websites that appeared on the World Wide Web. The inner planets retained smaller, denser cores whereas the outer planets possessed larger cores containing little metal or rock. Since they are so far away from the Sun they are able to hold onto their gas atmospheres and are made up mostly of gas but have solid rocky cores. Jupiter and Saturn are the outer gas giants. But this giant planet takes a long time to go around the sun. They orbit Jupiter as Jupiter orbits the sun. The “inner” planets, Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn, are also known as the “personal” planets. These classifications aren’t random; they provide important information about the nature and the function of the planets. Order of the planets Order of the eight planets from left: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune The order of planets from closest to farthest from the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. What is a planet? A planet’s density--the ratio of an object’s mass to its volume--reflects its composition; metals and rocks compose the denser inner planets while ices and gases make up the outer planets. The surface of the inner planets is characterized by volcanoes, canyons, craters, and mountains, and earth is the only one known to have water on its surface. A song to help students identify and learn about the eight planets in our solar system. Recently, rings have been discovered around two more giant planets — Jupiter and Uranus. Scientists expect to find rings around Neptune, too. The planet is tipped over so that it rotates like a top spinning almost on its side. ADDucation Tips: Click column headings with arrows to sort facts about our universe.Click the + icon to show any hidden columns. Uranus, Neptune and Pluto, are classified as “outer” planets in astrology. It is a small giant — fuzzy and blue — only four times bigger than Earth.

Adapted from the Scholastic "A Book About Planets and Stars" by Betty Polisar Reigot. Chariklo is a "small object" (aren't we all) that has two icy rings around it (don't we all). Venus has an average temperature of around 450 degrees C. Other than Earth, scientists believe that the only other planet in the solar system that could be hospitable to life is more than likely Mars. I thought it was about time we talked about Jupiter. Venus – Venus’ thick atmosphere makes it the hottest planet in our solar system. The hydrogen and helium are in the form of gas in the planets' atmospheres. Because Uranus and Neptune are primarily composed of, in this terminology, ices, not gas, they are increasingly referred to as … They are probably made mostly of water, ice, and other icy particles. No need to register, buy now! These planets are much larger than the inner planets and are called gas giants as they are composed primarily of hydrogen and helium. Atmospheres protect planets from the sun’s harmful radiation and prevent energy from flying into space. In fact, it’s almost big enough to be a star! Astronomers realized the flickering was due to rings that partly blocked the star's light for a few moments. Planets in our solar system can be divided into two main groups, Terrestrial Planets and Gas Giants. Venus Facts. At the center is a rocky core. View not found. Some interesting facts about the outer planets are that they are called gas giants. As the elements and gases moved and collided with one another, they began clumping together. Inner planets have a mostly iron core, surrounded by a mantle. The inner planets all have densities comparable to that of earth. There is a very great distance between the inner and outer planets. 1. The inner planets consist of those orbiting inside the asteroid belt--Mercury, Venus, Earth and Mars. Saturn has 33 known moons, and one of its moons, Titan, bears an eerie resemblance to the earliest stages of earth’s evolution. The four gas giants in our solar system are Jupiter, Saturn, Uranus, and Neptune. Rings around Saturn have been seen for many years. In our solar system we have eight planets: Mercury, Venus, Earth, and Mars are the inner rocky planets. Mars. Dinh received her Bachelor of Science in physiology from the University of California at Davis. Venus has temperatures over 450 degrees C and is listed as the hottest planet in our solar system. List of Facts About Our Universe & Galaxies Fascinating facts about our Universe, Milky Way, Galaxy and our solar system. It was the first spacecraft to deploy an entry probe into an outer planet's atmosphere. The outer planets include Jupiter, Saturn, Uranus and Neptune. THE OUTER PLANETS (GAS PLANETS) What are they and why are they called Gas? Now we know Jupiter has at least 17 moons. Our solar system came into being 4.6 billion years ago, as evidenced by the dating of space rocks called meteorites. When "Voyager 2" passed Uranus in 1986, it showed a close-up of the planet's rings. Maybe Titan's atmosphere and surface have stayed warm over billions of years. Sixty-four known moons orbit Jupiter, with Ganymede being the largest moon in the solar system, even bigger than Mercury. The outer planets have a lot of atmosphere. The intense gravities of the larger planets continued to capture stray gases to form thick, gaseous or icy atmospheres. The outermost part of these planets may be slushy. In fact, before 1978 the definition of a “planet” was not really necessary. The path of a comet though is far more elliptical than that of any planet. The solar system coalesced from a cloud of gas and dust particles, giving rise to the sun and the inner and outer planets. The outer planets have a lot of atmosphere. The moon named Titan, one of the largest in the solar system, has a lot of atmosphere. It happens every 248 years. Let’s explore some facts … The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune. The Coriolis effect, resulting from a planet’s rapid rotation, refers to the distribution of warm air to the pole regions, causing areas of high winds and calm. At the planet's heart lies the inner core, a solid sphere of iron and nickel that's 759 miles wide and as hot as 9,800 degrees Fahrenheit. The outer planets are further away, larger and made up mostly of gas. But inside the planet, it gets hotter and hotter closer to the center. In 2006 Pluto was excluded from the list of planets and has been classified as a dwarf planet. Jupiter has more than double the mass of all the other planets combined. Halley’s Comet only enters our inner solar system every 75 years. Saturn is almost 10 times bigger than Earth. 2. Particles emanating from the sun--the solar wind--interact with the magnetosphere to produce brilliant light shows at the north and south poles called auroras. 3. None. When scientists studied Uranus, they found that its orbit was slightly different from what they thought it would be. As well as facts, we offer a range of other things, such as pictures, history, wallpapers and more. Mercury Facts. Jupiter is so far away from Earth that it was hard to learn much about it with only telescopes. Our Milky Way galaxy has more planets than it has stars. But it takes 165 Earth years for Neptune to make one orbit around the sun. These are the eight planets of our Solar System; however, there is a ninth, or at least, there used to be a ninth planet, namely Pluto. Pluto is a puzzle. Planet Facts Read some really neat facts about the planets in our solar system! But he also posited that they are so spread out that if we were randomly inserted into the universe, the chances that we would be on or near a planet would be less than one in a billion trillion trillion, or 10-33. Jupiter is, after all, the biggest planet in our Solar System. This artist’s impression shows what those multiple Solar Systems might look like. They are much bigger than the inner planets.
