The rings would probably reflect so much sunlight that the planet would never fully plunge into darkness, but remain in a gentle twilight even in the depth of night. During the day, the rings could potentially cause light levels on Earth to skyrocket [source: Atkinson]. Read more
Earth's hypothetical rings would differ in one key way from Saturn's; they wouldn't have ice. Earth lies much closer to the sun than Saturn does, so radiation from our star would cause any ice in Earth's rings to sublime away. Still, even if Earth's rings were made of rock, that might not mean they would look dark.
It turns out that all of the planets, Earth included, did have rings at one time. ... Close enough to a planet, this might cause a moon to break apart, and also keeps the bits of material that form a ring from collecting together into a moon.
Earth may soon have its own set of rings, according to researchers at the University of Utah, US. These rings which may develop around our planet, however, will be made up of space debris. ... He and his team of engineers are now working to find ways to clean up the space junk, using magnets.
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.
Slow collision between lunar companions could solve moon mystery. Earth may have once had two moons, but one was destroyed in a slow-motion collision that left our current lunar orb lumpier on one side than the other, scientists say.
The Earth's orbit could be stable if the planet rotated around the two stars. The stars would have to be close together, and the Earth's orbit would be further away. ... Most likely, beyond the habitable zone, where the heat of the suns wouldn't be enough to keep our water in a liquid state.
Based on that assumption, Mars will also have rings in the future. On June 2, 2020, scientists from SETI Institute and Purdue University showed evidence of Mars having its own rings a few billion years ago, which explains why Mars' smallest moon, Deimos has an oddly tilted orbit.
Have you ever wondered what would happen if the Earth stopped rotating for even one second? ... We are all moving with the Earth at 800 miles an hour due East. If you stopped Earth and you weren't seatbelt buckled to the Earth, you would fall over and roll 800 miles an hour due East."
The top and the bottom faces would be polar, while the remaing four sides would enjoy an equatorial climate. However, if the Earth was a cube that rotated through its corners, then each side would have a temperate climate, you could say good bye to extreme temperatures and precipitation.
If the earth were much smaller, its molten iron core would have exhausted its heat and stopped producing a magnetic field. At which point the sun would have blasted the reduced earth's atmosphere away (the atmosphere is less attached due to smaller mass).
Three moons would cause much stronger gravitational effects, as well as centripedal and centrifugal effects. The axis of Earth's rotation may well be different, and that would affect the seasons. Animals and plants would have adapted quite differently.
The Earth doesn't have rings because the Moon has hoovered up any rocks that may have been in orbit. The Moon was originally in a lower orbit, but over millions of years has moved further away to where it is now. That means the Moon was close and picked up any rocks nearby.
If you're talking about majestic ice rings, like we see around Saturn, Uranus or Jupiter, then no, Earth doesn't have rings, and probably never did. If there was any ring of dust orbiting the planet, we'd see it.
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
The good news is that if the Sun were to explode – and it will eventually happen – it wouldn't happen overnight. ... During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.
If Earth's diameter were doubled to about 16,000 miles, the planet's mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently. RECOMMENDED VIDEOS FOR YOU...
Can a planet really have two suns? While many things about Star Wars are purely fictional, it turns out that planets orbiting two or more stars is not one of them.
The name "Earth" is derived from both English and German words, 'eor(th)e/ertha' and 'erde', respectively, which mean ground. ... One interesting fact about its name: Earth is the only planet that wasn't named after a Greek or Roman god or goddess.
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night, to 224 degrees Fahrenheit (106 degrees Celsius) during the day.
Long answer: The Moon is in a stable orbit around Earth. There is no chance that it could just change its orbit and crash into Earth without something else really massive coming along and changing the situation. The Moon is actually moving away from Earth at the rate of a few centimetres per year.
