What would happen if an asteroid hit the moon?
So what would it take to leave behind more than just a crater.
Well, an asteroid the size and mass of the moon itself would probably just destroy it or nudge it out of its current orbit around the Earth and cause drastic changes to our tides..
How long would it take to die if the sun exploded?
The sun will start to die when it runs out of fuel in about 5,000,000,000 years (that’s five billion years). This is 77 times longer than the Tyrannosaurus-Rex has been extinct … a very, very long time.
What would happen if there was no sun on earth?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe. The earth’s position in the solar system is optimal for the development of life.
Can life on 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.
How long would humans survive without the sun?
A relatively simple calculation would show that the Earth’s surface temperature would drop by a factor of two about every two months if the Sun were shut off. The current mean temperature of the Earth’s surface is about 300 Kelvin (K). This means in two months the temperature would drop to 150K, and 75K in four months.
What would happen if we nuked the moon?
The bomb itself would likely explode on the very edge of the dark side of the Moon, the part that just about wobbles into our terrestrial line of sight, so that the fire and fury could be seen back on Earth more clearly. The warhead could be unleashed above, on, or under the lunar soil.
How long can we live on Earth?
The end of earth will come in 7.59 billion years, unfortunately the end for all life on earth will come much sooner.
How long is the sun going to last?
The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. And, based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.
Why is the sun important to life on Earth?
The sun is the closest star to Earth. … It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce.
How long would it take for us to know if the sun died?
Answer 1: If the sun were to blow up, life on Earth would certainly end. It takes eight minutes and twenty seconds for light to travel from the sun to the earth, so we would not know that the sun had exploded until eight minutes and twenty seconds after the explosion occurred.
Can we survive without 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.
What would happen if the moon broke apart?
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.
