Many believe that this was caused by a collision with an Earth-sized planet. He was the father of Cronus / Saturn, which in turn, was the father of Zeus / Jupiter. Fun Facts about Uranus for Kids Because it’s tipped, Uranus has seasons that last 20 years. It has the fourth-largest mass in the Solar System. It comparison to Earth’s mass, Uranus has around 14.5 times the mass of Earth. The wind speeds on Uranus are another extreme, reaching up to 560 mph/900 kph. The temperature on Uranus is 197 degrees C (79 K) near the top of its atmosphere, but its small solid core (about 55% the mass of Earth) is probably about 5,000K. One Uranian day on Uranus is about 17 Earth hours. It consists mainly of ice and only a fraction of rock. Something prevents the heat from Uranus’s core from reaching the surface. In 2018 a global research team discovered that the clouds of Uranus are made up of hydrogen sulfide. It has an irregular magnetosphere which is tipped over on an axis of almost 60 degrees from the axis of rotation of the planet. They couldn’t be detected from earth because they are so far away and their reflection of light was also low. If we tried to send a spacecraft to Uranus there wouldn’t be anywhere to land, and besides, the extreme temperatures and pressures would destroy the spacecraft. Uranus and Neptune are the two ice giants located in the outer solar system. Uranus is the lightest out of all the four gas giants. The situation of the tilt creates a condition so that its northern pole and southern pole only face the sun half of the year each. Uranus has a thick atmosphere made of methane, hydrogen, and helium. The atmosphere of Uranus can get as low as 49K(-224.2 degrees C), and this makes the planet colder than the other ice giant, Neptune. It has a very deformed landscape with strange and hard to explain patters. Uranus was first discovered in 1781 by astronomer William Herschel who thought at first that it was a star or comet. Scientists think that the core is mostly made up of rock and ice and the mantle is around 13.3 times the mass of the Earth and made up of water, ammonia, and other elements. These are above a rocky core and near the core are temperatures of 9,000 degrees F/4,892 degrees C. The inside of Uranus is believed to contain two layers which are the core and a mantle. Uranus got its name from the father of the Roman god, Saturn. However, it contains more “ices” such as water, ammonia, methane, and traces of other hydrocarbons. Uranus is the seventh planet from the sun.eval(ez_write_tag([[580,400],'planetsforkids_org-medrectangle-3','ezslot_2',601,'0','0'])); The planet Uranus is one of the gas giants and in our solar system, it’s huge diameter makes it the third largest and the fourth in mass. In 1789 scientists named the radioactive element, uranium, eight years after the planet Uranus was discovered. The thick atmosphere is made of hydrogen and helium like Jupiter and Saturn. Around 80% of the mass of Uranus is made up of dense, hot fluid of “icy” materials including water, methane, and ammonia. There wouldn’t be any way for an organism to adapt or thrive. It is also the coldest planet in the Solar System with temperatures dropping as low as -224 degrees. Uranus is 2.9 billion kilometers / 1.8 billion miles away from the Sun. However, since it has a different composition, both Uranus and Neptune are termed, ice giants. Looking for fun activities to teach kids about the planet Uranus? In our solar system we have eight planets: Mercury, Venus, Earth, and Mars are the inner rocky planets.eval(ez_write_tag([[580,400],'planetsforkids_org-box-3','ezslot_1',197,'0','0'])); Jupiter and Saturn are the outer gas giants. NASA’s Voyager 2 took 9 years and traveled 1.8 billion mi/3 billion km, gathering important information about our solar system. The planet is tilted on its axis so much that it is sideways. Facts about Uranus for Kids: Uranus has the coldest temperatures of all of the planets, hitting as low as -224 degrees C. Uranus has a tilted axis and it’s thought that a collision with another large celestial object was the cause of it. When sunlight passes through the atmosphere it reflects light back through the top of the clouds. In recent years, astronomers have designed a new class called the “dwarf planets.” These are smaller worlds, not quite big enough to be considered a standard planet, and include Pluto. In comparison to Earth, Uranus has four times its diameter. Uranus is sometimes visible in the sky. The difference between Uranus and other gas giants also relates to the mantle as it may be “icy” but it’s also hot and thick. Uranus has a blue-green color from all of the methane gas in its atmosphere. Uranus Has A Lot Of Ice. It is a gas giant. The reason why Uranus is blue is due to the presence of methane. Uranus is an ice giant (instead of a gas giant). Temperatures are on average at around -224 degrees Celsius / -371 degrees Fahrenheit. It took 2 years before astronomers accepted Uranus as an actual planet. The rings around Uranus are different than those that we find around Saturn, which are mostly dust and ice and relatively small. Uranus has a radius of 25.362 km / 15.759 mi and a diameter of 51.118 km or 31.763 mi. The other set has some that are a reddish color and another that is blue. Uranus is the only planet in the Solar System that spins on its side. It is mostly made of flowing icy materials above a solid core. You won’t need binoculars or a telescope to see it, but you can only view it on a very clear night sky. The planet was too dim to be seen by ancient civilizations and as such it remained hidden in the darkness of the sky. Uranus has been visited only once by a spacecraft, namely, Voyager 2. In good conditions, Uranus can be seen without binoculars. The rings of Uranus are unique since they are dark and extremely narrow. Both Uranus and Neptune are blue because they have methane. Uranus has a radius of 25.362 km / 15.759 mi, and a diameter of 51.118 km or 31.763 mi. However, it takes 84 Earth years for Uranus to complete its orbit around the sun, also known as a “Uranian year.”. In the case of Uranus, the chemical element Uranium, discovered in 1789, was named after the newly discovered planet. Jupiter, the largest planet in the Solar System, has 2.8 times the diameter of Uranus. Uranus has two sets of rings, with the inner ring being made of a set of dark grey, thinner 9 rings.
