Fifth in line from the Sun, Jupiter is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined.

Does the Sun move?

Yes, the Sun - in fact, our whole solar system - orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way!

Which is the hottest planet?

Venus' thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

Which planet is the brightest?

Venus is always the brightest and no planet will ever surpass it in brightness unless it goes supernova.

What is the brightest object in the sky?

As the Moon is the closest celestial object to us, it appears the largest in the night sky. Hence, it is the brightest object in the night sky. The second brightest object is the planet Venus due to its highly reflective atmospheric content.

What planet is bigger than Sun?

To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. At about 13 times the mass of Jupiter a planet becomes what is referred to as a "brown dwarf". These objects are really small stars, as fusion begins at this point.

Is Jupiter Blue?

Jupiter isn't the most colorful spot in the solar system. It looks like a watercolor swirl of white, orange, brown, yellow and bit of dull red like we see in the Great Red Spot. A NASA image released Friday shows Jupiter looking very deep blue, a color we more strongly associate with our own planet.

What is the biggest universe?

The biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
