A Bubbly Cosmic Celebration

In the brightest region of this glowing nebula called RCW 34, gas is heated dramatically by young stars and expands through the surrounding cooler gas. Once the heated hydrogen reaches the borders of the gas cloud, it bursts outwards into the vacuum like the contents of an uncorked champagne bottle — this process is referred to as champagne flow. But the young star-forming region RCW 34 has more to offer than a few bubbles; there seem to have been multiple episodes of star formation within the same cloud.

Hi! On your main blog you reblogged a gif of the planets. Why does it jupiter so long to complete a rotation?

Because Jupiter is so much further away than the inner planets.

The Earth is 149,600,000 km from the Sun.

Jupiter is 778,500,000 km from the sun

778,500,000/149,600,000 = Jupiter is ~5.20 times further away from the Sun than the Earth.

And with orbits they are not necessarily completely linear to distance because this depends on the velocity of the planets. If so then 1 jupiter year would be about 5.20 Earth Years, but this isn’t the case. 

A year on Jupiter is ~12 years on Earth. I believe this owes to the fact that the larger the orbit, the slower the velocity of the planet. Mercury orbits 1.6 times faster than Earth, while Jupiter orbits at about 0.43 times Earth’s speed. And so Jupiter takes a longer time relative to Earth to complete its orbit.
