What if Earth was a moon of Jupiter?

Since Jupiter's gravitational pull accelerates these objects to a collision speed of about 216,000 km/h (134,000 mph), at the minimum. If Earth became one of Jupiter's moons, we're now in the line of fire. As a much, much smaller planet we're less likely to be able to absorb those kind of impacts.

Could Earth have been a moon of Jupiter?

Life on Earth or Mars could have been brought to the moons of Jupiter or Saturn on rocks blasted off those planets, researchers say.

What if Earth had 2 moons?

The consequences of a second moon orbiting the Earth depend on how massive that moon is and how far from the Earth it orbits. The most obvious effect would be that the ocean tides would be altered. Tides could be either smaller or higher and there could be more than two high tides per day.

Is Titan habitable?

Thus, Titan could potentially harbor environments with conditions suitable for life—meaning both life as we know it (in the subsurface ocean) and life as we don't know it (in the hydrocarbon liquid on the surface).

What if Earth had rings?

At the equator, the rings would appear to divide the sun, casting a dramatic shadow over half the world. Likewise, the rings themselves would cast shadows on Earth.

What If the Earth Was a Moon of Jupiter?

What if Earth rotated backwards?

If the earth abruptly changed its rotational direction, probably many things we see every day would be destroyed. Skipping over the transition, however, an earth rotating in the opposite direction would, among other things, cause the sun, moon and stars to appear to rise in the west and set in the east.

Is the water on Titan drinkable?

Titan is going to have methane and ethane tainting the ice. And Enceladus and Europa are going to be all kinds of salts and possibly magnesium sulphate, or epsom salts if it's hydrated. So if you drink that water you'll be trotting off to the loo quite soon.

Can humans live on Europa?

Europa's surface is blasted by radiation from Jupiter. That's a bad thing for life on the surface – it couldn't survive. But the radiation may create fuel for life in an ocean below the surface. The radiation splits apart water molecules (H2O, made of oxygen and hydrogen) in Europa's extremely tenuous atmosphere.

Is terraforming Mars possible?

So can we do it? The short answer is no. Using data from rovers and spacecrafts that have been monitoring Mars, the team in the study identified all of the planet's possible reservoirs of carbon dioxide and their potential contributions to the atmosphere.

What planet rains diamonds?

Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.

Can a moon have a moon?

Yes, in theory, moons can have moons. The region of space around a satellite where a sub-satellite can exist is called the Hill sphere. Outside the Hill sphere, a sub-satellite would be lost from its orbit about the satellite. An easy example is the Sun-Earth-Moon system.

What planet has 21 moons?

In 1999 three new moons were discovered orbiting Uranus, a great gasball of a planet about 2 billion miles from Earth. The discovery raised the number of Uranian moons to 21, the most, as far as is known, in the skies of any planet.

Is the water on Europa drinkable?

The best places to look for life are where the ocean overlies warm rock. This may be the case inside Europa (Jupiter) and Enceladus (Saturn), but chemical reactions with the rock would make the liquid water salty, so not good to drink.

Would Venus be habitable?

If it's too much or too little, then liquid water can't exist on the surface, and thus the planet is not a good candidate for life. According to this simple criterion, Venus is habitable; that is, it can potentially support liquid water.

Can we colonize Jupiter?

Jupiter itself, like the other gas giants, is not generally considered a good candidate for colonization. There is no accessible surface on which to land, and the light hydrogen atmosphere would not provide good buoyancy for some kind of aerial habitat as has been proposed for Venus.

Is Titan bigger than Earth?

It is also about 1.19 times as massive as Earth's overall, or about 7.3 times more massive on a per surface area basis. Opaque haze layers block most visible light from the Sun and other sources and obscure Titan's surface features. Titan's lower gravity means that its atmosphere is far more extended than Earth's.

Can Titans support human life?

The methane and ethane in the atmosphere of Titan is similar to the water in the Earth's atmosphere, and could potentially allow Titan to maintain human life.

Does Titan have an underground ocean?

The subsurface ocean inside Saturn's largest moon, Titan, could be as salty as any body of water here on Earth, a new study reports. Gravity data collected by NASA's Cassini spacecraft suggest that Titan's ocean must have an extremely high density.

What would happen if the Earth stopped spinning for 42 seconds?

All of the land masses would be scoured clean of anything not attached to bedrock. This means rocks, topsoil, trees, buildings, your pet dog, and so on, would be swept away into the atmosphere.

What if the Earth stopped spinning for 1 second?

"It would kill everyone on Earth. People would be flying out of windows and that would be just a bad day on Earth," Tyson had added. In addition to this, Tyson also clarified that if everyone on Earth accomplishes to slow down during such an event, along with the planet, then no one would get hurt.
