Will Jupiter and Saturn collide?
Bottom line: Jupiter and Saturn will have their 2020 great conjunction today, which is also the day of the December solstice. These two worlds will be visibly closer in our sky than they’ve been since 1226. At their closest, Jupiter and Saturn will be only 0.1 degree apart.
What if Jupiter crashed into Saturn?
The new planet would wobble a bit and then settle down. It would be quite hot, causing it to grow significantly in size. It would appear brighter from Earth, both from the reflection by the greater surface and from its own heat, but it wouldn’t be enough to heat Earth or bombard it with heavy radiation.
What would happen if an asteroid hit a gas giant?
hitting any of them causes much of the mass of the asteroid to almost instantly convert into plasma, with explosive results. As far as the gas giant…it gains some weird storms and shock waves, but in the end it is just gas, so there’s no physical remains of the impact.
What would happen if a gas giant hit Earth?
If an earth sized planet collides with a gas giant. Or, the planets could be colliding at great speed. Then the same thing will happen. Only difference is that most of the pieces of the destroyed planet will be flung into space as there is greater momentum in the system and hence velocity.
What if the sun was a blue giant?
The colour of a star is directly related to the temperature of a star. Sun is more or less a normal star with surface temperature around 6000K and yellow in colour. So imagine if sun would be a blue star, it would be so hot that it would become nearly impossible for a planet at a distance as earth to sustain life.
What happens if Jupiter hit Earth?
As the Earth is pulled into Jupiter, our planet’s velocity could increase until it reaches 60 km/s (37 mi/s). Our planet is too small and would burn up in the atmosphere before that ever happens. This would have a huge impact on Jupiter, as the Earth’s remains would completely mix into its atmosphere.
What would happen if Saturn hit Earth?
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. Fault lines would rupture, volcanoes would blow their tops, and anything left on the surface of the Earth would be wiped out. And then comes the final blow.
