What if a planet hit the Sun?

If the planet somehow survived and punched its way to the centre of the Sun, then much less energy would be deposited in the convection zone and the effects would be lessened. On longer timescales the Sun would settle back down to the main sequence, with a radius and luminosity only slightly bigger than it was before.

Can a planet fall into a Sun?

The planets do not fall into the sun because they are moving too fast in the tangential direction. As they fall toward the sun they travel tangentially just enough that they never get very close to the sun.

What would happen if a planet hit Jupiter?

As we crash into Jupiter, both planets' atmospheres will be compressed, rapidly increasing the temperature, and essentially setting the air on fire. But at least we won't have to worry about colliding with Jupiter's core, because we'll never make it there.

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 Uranus crashed into Earth?

Because Uranus is about 15 times more massive than the Earth, its gravitational pull would start massively affecting our planet. Volcanoes would begin erupting uncontrollably, and tremendous earthquakes would get in on the act, destroying Earth from the inside. And the stink.

Timeline: What If Life Had Instant Karma

What if sun exploded?

For Earth to be completely safe from a supernova, we'd need to be at least 50 to 100 light-years away! But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn't be strong enough to destroy the whole Earth. Only the side facing the Sun would boil away instantly.

Will the Sun ever burn out?

Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies. One way or another, humanity may well be long gone by then.

How long would we live if the Sun exploded?

You might be able to survive for a bit longer than you think. If the sun suddenly blinked out of existence, you'd have nothing to worry about — for the first eight minutes, anyway. After that, all hell would likely break loose. Still, it wouldn't be the instantaneous end to life on Earth that you might think.

Can the Sun swallow Earth?

Drag from the chromosphere of the Sun would reduce Earth's orbit. These effects will counterbalance the impact of mass loss by the Sun, and the Sun will likely engulf Earth in about 7.59 billion years. The drag from the solar atmosphere may cause the orbit of the Moon to decay.

Will the moon crash into Earth?

Short answer: Technically it's possible that the Earth and Moon could collide in the very distant future, but it's very unlikely. It's certainly not going to happen while any of us are alive. Long answer: The Moon is in a stable orbit around Earth.

What if the Earth was 10 feet closer to the Sun?

You might have seen somewhere that if Earth were 10 feet closer to the sun, we would all burn up, 10 ft further and we'd freeze to death. As claims go, you'll be hard pressed to find one more wrong than this one. During the first week of the new year, Earth moves closer to the Sun at about by about a mile each hour.

Can Earth become a star?

No. In order for a star to sustain itself, fusion must take place to avoid collapse due to gravity. The earth is made from heavy elements (nickel, iron, etc) which are nearly impossible to fuse in stars. Therefore, due to this, the Earth cannot be a star due to the addition of more mass.

Can a black hole pull in a planet?

Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.

Is Saturn a failed star?

Gas giants are also called failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System.

How long will the Earth last?

The upshot: Earth has at least 1.5 billion years left to support life, the researchers report this month in Geophysical Research Letters. If humans last that long, Earth would be generally uncomfortable for them, but livable in some areas just below the polar regions, Wolf suggests.

Can a planet explode?

As far as astronomers know, there is no internal mechanism or other phenomenon that could ever cause a planet to fly apart. Contrary to science fiction, planets are stable and causing one to explode would require some chemical or nuclear process which can provide an explosive punch of energy.

How old is the world?

Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.

What if the Moon disappeared?

It is the pull of the Moon's gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth's tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

Will the sun burn out one day?

The sun's death rattle

All good things eventually come to an end. And one day, about 4 billion or 5 billion years from now, the sun will burn through its last gasp of hydrogen and start burning helium instead.

What would happen if a black hole hit Earth?

Bad News for Earth

The same gravitational effects that produced spaghettification would start to take effect here. The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.

What happens if we land on Pluto?

But when Pluto is farthest from Earth, that message would travel for over 6.5 hours before reaching its destination. Depending on where it is in its orbit, you can expect freezing temperatures on Pluto that vary from minus 369 degrees Fahrenheit (minus 223 Celsius) to minus 387 F (minus 233 C).

What if Saturn crashed into Earth?

That would cause disaster on a global scale, mostly in the form of apocalyptic floods as huge tidal waves marched across the planet, destroying everything in their path. By the time Saturn is at the same distance as the Moon, its tides would be many thousands of times stronger than the Moon's.
