What if an asteroid hits the Moon?
The Moon is very big, and any small object hitting it would have very little effect on its motion around the Earth, because the Moon’s own momentum would overwhelm that of the impact. Most asteroid collisions would result in large craters and little else; even the largest asteroid known, Ceres, wouldn’t budge the Moon.
What would happen if the Moon were destroyed?
Destroying the Moon would send debris to Earth, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
What would happen if the Moon got hit?
If the moon exploded, the night sky would change. We would see more stars in the sky, but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter, and our ocean tides would be much weaker.
What would happen if the Moon crashed into Earth?
What would happen if the Moon crashed into Earth? Everything on Earth would die. The only way to survive this collision would be to leave Earth. The Moon and Earth would both be destroyed; the Earth would probably be split into numerous smaller pieces.
Is the flag still in the Moon?
Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing.
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).
What if Earth had 2 moons?
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.
Can we survive without moon?
Winds could become much faster and much stronger without the moon. … The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
Can Earth survive without the sun?
Without the Sun’s rays, all photosynthesis on Earth would stop. … While some inventive humans might be able to survive on a Sun-less Earth for several days, months, or even years, life without the Sun would eventually prove to be impossible to maintain on Earth.
Will the moon ever collide with Earth?
In fact, scientists think that a massive planetary object, known as Theia, collided with the Earth 4 billion years ago, resulting in the formation of the Moon. “Exceptionally unlikely.” … So the Moon’s orbit is getting further away from Earth, not closer, and certainly not on a collision course with our planet.
What if Jupiter exploded?
Jupiter, which has a mass three times the combined mass of all the other planets, dominates gravitational interactions within the Solar System. … With Jupiter gone, the main effect on Earth would be an increase in the rate of impacts from asteroids and other space flotsam.
What would happen if the sun died?
In five billion years, the sun is expected to expand, becoming what is known as a red giant. “In this process of the sun becoming a red giant, it’s likely going to obliterate the inner planets … … Once the sun completely runs out fuel, it will contract into a cold corpse of a star – a white dwarf.
Will the Moon ever explode?
Moons do sometimes explode. This can happen in two ways — they can be struck by something big, or they can be ripped apart by gravitational disturbances. … Exploding moons and planets were much more common when the Solar System was young. At that time the Solar System was a chaotic place.
What happens if the Moon is red?
A “blood moon” happens when Earth’s moon is in a total lunar eclipse. While it has no special astronomical significance, the view in the sky is striking as the usually whiteish moon becomes red or ruddy-brown. … Earth passes in between the moon and the sun and cuts off the sunlight, causing an eclipse.
