Uranus is one of the outer planets which we call gas giants and Uranus is also the seventh planet from the sun which was discovered in 1781 by an astronomer named William Herschel. Uranus was the first planet to be discovered in Modern times. Uranus is named after a Greek god of the sky in Latin. Before Uranus was discovered it was thought to be a comet but it was not fuzzy looking so it couldn’t be. It’s so far from the sun that it takes 84 years just to make one complete orbit around the sun. In fact it is estimated that Uranus is 1,780,000 miles from the sun and because it’s so far away for 200 years we could not determine how quickly it turned on its axis. Until a while ago we found out that it actually spends on its side and is called by some people the “sideways planet”. Nights on some parts of Uranus actually last about 40 years because of the way it spins.
Uranus’s atmosphere is composed of primarily of hydrogen and helium and only a small amount of it is methane and traces of water which is what Uranus gets its blue green color from (methane gas). Uranus has no solid surface and was once considered one of the bladder looking planets. Uranus was also revealed as a dynamic with some of the clouds in the outer solar system. One day there was a satellite discovered on Uranus in 1948 called Miranda and Miranda looked like it was pieced together from parts that didn’t quite merge properly. The Miranda was also about 500 km in diameter.
Uranus has at least 27 moons or more. Some of Uranus’s moons are Oberon, Titania, Ariel, Umbria, Cupid, Rosalind, Desdemona, Belinda, Stephano, Bianca, Juliet, and Puck. From here on earth Uranus’s moons seem to go up and down.
