Although Neptune comes in fourth in terms of diameter, it ranks third in terms of mass, ahead of Uranus. The gas giant weighs in at 1.02 x 1026 kilograms, or 102 trillion trillion kilograms. It is more than seventeen times as massive as Earth. The rock, ices, and gas that make up th...
Mercury's diameter is3,030 miles (4,878 km), comparable to the size of the continental United States. This makes it about two-fifths the size of Earth. It is smaller than Jupiter's moon Ganymede and Saturn's moon Titan. How big is Mercury compared to the Earth? With a radius of ...
How wide is the asteroid belt in kilometers? What is the diameter of the asteroid belt? How big is the asteroid belt between Mars and Jupiter? How many miles wide is the asteroid belt? What is the smallest asteroid in the asteroid belt? How dense is the asteroid belt? What is the cir...
“How big is the moon? This one is an easy approximation to remember. It’s about 1/4 the size of Earth. Specifically, it’s 27% in diameter.” The moon is as wide as the United States. From the west to the east coast, the whole United States can fit on the moon. If you mea...
A telescope's ability to collect light is directly related to the diameter of the lens or mirror -- the aperture -- that is used to gather light. Generally, the larger the aperture, the more light the telescope collects and brings to focus, and the brighter the final image. The tele...
How many astronomical units is the asteroid belt from Earth? How many Jupiters can fit in the sun? What is the diameter of the Earth's moon? How many moons can fit inside the sun? How big is the sun's magnetosphere? How many light minutes are there in one astronomical unit?

ELEVEN Earths would fit across the diameter of Jupiter. Mercury spins so slowly that a year is longer than a day! Mercury has a very thin atmosphere. Venus is the hottest planet in the solar system with air so thick it would crush human visitors in seconds. Olympus Mons on Mars is three...
while ago, but Jupiter is a long way from being a star. That estimate was based on some old nuclear physics (like 1980’s old). By being awesome, and buildingneutrino detectors and big computers, we’ve managed to refine our understanding of stellar fusion a lot in t...
Earth is the fifth-largest planet in the solar system, behind Jupiter, Saturn, Uranus and Neptune. With a diameter of 86,881 miles (139,822 km), Jupiter— the largest planet in the solar system — is 11 times wider than Earth. The gas giant has a volume of 343 trillion cubic miles...
