My project is on uranus

Compared to the Earth Uranus's mass 14.5 and Earths is 1

Uranus is 4 times bigger than Earth in size

Uranus takes 84 Earth years to orbit the sun

It takes Uranus 17 hours, and 14 minutes to rotate

Traces of hydrocarbons are also present in the air around Uranus. Ices made up of water, ammonia, and possibly methane also exist in the atmosphere. Atmospheric composition by volume: Molecular hydrogen: 82.5%. Helium: 15.2%. Methane: 2.3%.

It has been recently found that wind speeds on Uranus range from 90 to 360 mph and the planet's average temperature is a frigid -353 degrees F. The coldest temperature found in Uranus' lower atmosphere so far is -371 degrees F., which rivals Neptune's frigid temperatures.

The names of Uranus' moons are Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Mab, Belinda, Perdita, Puck, Cupid, Miranda, Francisco, Ariel, Umbriel, Titania, Oberon, Caliban, Stephano, Trinculo, Sycorax, Margaret, Prospero, Setebos and Ferdinand. The moons are named after characters from William Shakespeare's works and characters by Alexander Pope.

It is interesting on how cold Uranus can get and I have been waiting for a new record on how cold it could get

 that's why I chose it.

The voyager 2 in 1781. Voyager 2 got to Uranus 196 years before it was launched. Voyager 2 reached Uranus in January 1986 over 9 years after it was launched in August 1977

1. Uranus is the coldest planet in the Solar System:

Uranus is the seventh planet from the Sun, orbiting at a distance of 2.88 billion km. But it’s still much closer than Neptune, which averages a distance of 4.5 billion km from the Sun. However, this does not prevent Uranus from being colder than Neptune. Whereas the former experiences an average temperature of 72 K (-201 °C/-330 °F), reaching a low of 55 K (-218 °C/-360 °F).

2. The axial tilt of Uranus is a staggering 99 degrees! In other words, the planet is rotating on its side. All the planets look a bit like spinning top as they go around the Sun, but Uranus looks more like a ball rolling in a circular pattern. And this leads to another strange fact about Uranus…

3. Like all of the giant planets, Uranus has its share of moons. At present, astronomers have confirmed the existence of 27 natural satellites. But for the most part, these moons are small and irregular.If you were to add up all of their masses, they would still be less than the half the mass of Triton, Neptune’s largest moon. However, unlike Triton, Uranus’ larger moons are all believed to have formed from an accretion disk that surrounded the planet, rather than being captured objects.

4. Most of the planets are visible to the unaided eye, and were known in ancient times. Uranus was the first planet discovered after the invention of the telescope. It was first recorded in 1690 by John Flamsteed, who thought it was a star in the constellation Tauri. But it wasn’t until Sir William Herschel made his observations in 1781 that astronomers finally realized it was a planet.
