So, how fast does Earth spin? The actual speed of the Earth’s rotation is about 1,000 miles per hour as measured from the equator, so it might seem strange that people can’t actually feel the Earth spin. The reason is essential, that we are just used to it. Since the Earth spin...
the planetesimals accreted into protoplanets, and soon into the eight planets we currently know and love; those in the inner solar system, including Mercury, Venus, Earth, Mars, and those in the outer solar system - Jupiter, Saturn, Uranus and Neptune (sorry, Pluto - you're only a dwarf...
How long does it take for Uranus to orbit the sun? Suppose the moon started revolving faster. What effect would this have on the moon's phases? Would they be the same or different? How long does it take Ceres to orbit the sun?
Although the HST is responsible for countless incredible images and discoveries, it does have a few limitations. One of these limitations is that the HST can't observe thesunbecause the intense light and heat would fry its sensitive instruments. For this reason, the HST is always pointed away ...
In our solar system, we have small rocky planets (Mercury, Venus, Earth, Mars) and gas giants (Jupiter, Saturn, Uranus, Neptune). The planets formed when material from the early solar disk (planetismals) collided and clumped together to form the planets. The material in the inner solar ...
Why does Venus rotate backward from the other planets? How long is one solar cycle? How many times did Alan Shepard orbit the Earth? How long is the magnetic solar cycle? How does Uranus' tilted axis affect its seasons? What relationship between the Earth and the Sun causes the seasons to...
Uranus has 27 moons. The larger moons of Uranus likeArielare made of water ice and rock in nearly equal proportions. Neptune has 14 moons.Triton,one of these moons, has volcanoes of not lava but ice! Finally, even Pluto, which is no longer considered a planet, has 5 moons of its own...
The five other large moons in our solar system all have about our Moon’s gravity (0.13 to 0.18g, versus 0.16g). And Mars and Mercury have the same gravity, 0.38g. The only other bodies between 0.09g and 2.3g all are within 12% of 1g: Venus, Saturn, Uranus, and Neptune. All fou...
I understand that you said that Jupiter is about 4 AU(I’m rounding these numbers) from us, but that cannot be counted as an out. Neptune was discovered mathematically, not visually because we noticed an irregular tug on Uranus’ orbit. That’s a distance of roughly 11...
Uranus is a weird world in many ways. The most unusual thing aboutUranusis that it's tipped over on its side, and "rolls" around the Sun on its side. That means one axis or the other is pointed at the Sun during part of its 84-year orbit. The planet does rotate on its axis onc...
