Imagine how it would look if the Orion nebula is only four light years away - the distance the nearest star is to us, instead of 1,300 light years. It would be so bright that we wouldn’t be aware of the dark sky. We wouldn’t see other stars. The whole world would be the Orion nebula and the sun.

URANUS part 5 - Uranus’ moons

There are a lot of inner moons around Uranus. Moons that are very small and close to the planet. They tend to have very fast orbits on the order of maybe a day. Other moons zip around Uranus in just 12 hours. With Uranus’ moons speeding around the planet like race cars, it’s only a matter of time before two of them end up in a cosmic collision.

Circling the planet is a swirling system of moons. Even within the last decade, substantial changes have been detected in their unruly orbits. You can be certain that in a period of million or a few million years some of them will collide with each other. It will be a bad day for the moons but a welcoming event for the planet’s rings system. The debris that released from that can generate a new ring around Uranus.

URANUS part 4 - Uranus’ rings

When astronomers aimed the telescope at Uranus they were planning to watch the passage of the planet in front of a star. But as Uranus closed in, the star suddenly winked. In fact it seemed to flickered on and off five times as it neared the planet and then several more times as it emerged on the other side. What cause this strange phenomenon? The flickering star was actually passing behind five planetary rings - features that had only been seen on Saturn.

And observations made by Hubble Telescope in 2005 found a second set of rings orbiting almost twice as far away from the planet as the previously known rings.

Unlike Saturn’s thick icy rings, Uranus’ are dim and thin, comprised of dark rocky dust. Some of Uranus’ dusty rings were likely formed by the impact of a meteor or a comet with one of the planet’s 27 moons. The inner rings could be the result of the collisions between the moons themselves.

URANUS part 3 - How it was formed

As the proto-planetary disc of gas and dust in our solar system settled Jupiter and Saturn gathered up the most material and became the largest of the gas giants. As Jupiter and Saturn’s orbits grew they destabilized the planetary system as a whole . Dynamic interactions pushed Uranus and Neptune outward to the edge of the solar system at an accelerated rate where they feasted on icy objects. They have a lot of that initial gas but they also gathered a lot of icy material and some rocky material in the formation. So consequently,although they have this surrounding envelope of hydrogen, helium, methane, nitrogen, and some other stuffs they also have a lot of icy material in the inside. These icy interiors have led some to call Uranus and Neptune the ice giants.

URANUS part 2 - the Beautiful Rebel

Uranus is unique among the gas giant planets is that it is the only one who doesn’t have an internal heating source.

Uranus has the most off-kilter axis of any planet in the solar system. At 98 degree, the planet is actually spinning on its side. Its tilt is so extreme that, in a sense, the whole Northern hemisphere is the arctic and the whole Southern hemisphere is the antarctic.

URANUS part 1 - Facts about Uranus

Uranus is a mesmerizing blue marble. It’s really strikingly beautiful and different from the other planets. The almost pure featurelessness of it, it seems unreal.

It was the first planet discovered by telescope, by astronomer William Herschel in 1781.

Named after the Greek God of the Sky.

The time for Uranus to orbit the sun is 84 years.

Uranus owes its blue-greenish color to methane. The methane absorbs red and orange wavelengths from sunlight but reflects blue and green. And its soft appearance is due to smog.
