We’re flying past the planets of our solar system. We pass by Mars, Jupiter, Saturn, Uranus, and Neptune.
Then we move through dark space beyond the edge of our world. We’ve reached our destination.
It’s the Oort cloud, it’s a hypothetical region around the solar system that holds tonnes of asteroids and blocks of ice.
It’s likely to be where the largest comet in human history was born in now. It’s heading toward the sun.
For Darden le Bernstein was discovered totally by accident during the dark energy survey our telescopes were pointed at distance space.
Their main goal was to learn more about how the universe was expanding.
Astronomers also wanted to make a more detailed map of the observable universe.
Scientists analysed over 80,000 images in found a moving object, it was alarmingly close to our home planet.
Its size was an impressive 62 miles. That’s about the width of Lake Michigan.
It was already active comment with a long tail. Usually comments get a tail when they come close to the sun.
The heat from the Star Wars the comets surface in light materials like ice, begin to evaporate.
This forms a cloud of steam and dust that stretches far beyond the content, but Bernard Nellie Bernstein is too far away from the Sun to start heating up.
This means that its surface has a different composition. It might be solid carbon monoxide. This increases the luminosity of the comment. That’s why it can be observed with telescopes on Earth.
We can compare Bernard and Elie Bernstein to the largest media right to ever fall on Earth, about 66 million years ago, our planet was hit by a meteor writes about six miles wide.
At that time, the blast wave from the collision went around Earth several times, tsunami waves caused by the impact were taller than the largest skyscrapers in the energy from the explosions and huge areas on fire.
Almost all living creatures, including dinosaurs in ancient fish cease to exist. The meteorite left a crater three times the size of Manhattan.
The place where it fell was rich in Sulphur this substance evaporated because of the abnormal peat in gathered into massive clouds.
This constant acid rains that were falling on Earth for several more weeks. Our newly discovered comets is 10 times bigger.
If it weren’t flying toward Earth, you see with the unaided eye long before the impact. It looked like a moving star in the night sky.
A few days before the comet reached our planet, you’ll see it, even during the day, you’d be able to distinguish its long tail.
When the comet entered the atmosphere, they produce a booming sound so loud you hear it on the other side of Earth.
At this point, and comet would begin to heat up because of friction with the air.
It started burning countless pieces of debris would break away from the main body of the meteorites in thoughts, who, as soon as Bernard and Elie Bernstein touched the surface of the planet.
We see a flash so bright to get out shine the sun in a fraction of a second a colossal amount of energy would be converted into heat.
This would create the most powerful explosion in the history of our planet.
It literally rip out chunks of ground and throw them into the air, the blast wave would incinerate everything within a few 100 lines. We’ve continued to spread in different directions, breaking inventing trees.
At one point in reach snow capped mountains and trigger huge avalanches, that would cover many villages have lost weight we go around the planet, shattering glass and buildings on all continents.
Tsunami waves would be so high they would cover entire coastal cities, the most powerful earthquake in history would break the ground in create cracks. After the impact millions of tonnes of dust and ash would rise into the air.
A giant black calm, completely blocked the sun’s rays Earth would be plunged into darkness, all the debris in the air would start melting, they turn into liquid lava and fall back to the surface causing even more damage.
The ash and dust in the air would cover the sun for several more months.
During this time, the temperature on Earth would drop by several degrees, even if they were hiding in deep shelters in bunkers, people, as well as all other living organisms on the planet would be unlikely to survive this event.
Unfortunately, we’re not an Ellie Bernstein isn’t going to approach her.
Right now, the comment is about 20 astronomical units away from the sun. That’s 20 times the distance from Earth to the Sun.
It means the comet will soon cross the orbit of Uranus in 2031. It’ll be 11 astronomical units away from our star. that’s just outside Saturn’s orbit.
This is going to be the closest Bernard anelli Bernstein will approach the sun, then it will begin its flight back to the edge of the solar system, when the comet is bound to return again.
It’ll move away from the sun and slow down until the stars gravity pulls it back.
Then the comet will make another circle around our solar system, but that will take about 3 million years. Right now, we have other meteorites to worry about, for example, 3200 faith.
It crosses the orbits of Mars, Earth, Venus and Mercury, then it goes around the sun, and comes back.
This cycle takes about 523 days, then it starts over again, this meteorite is considered potentially hazardous because it crosses Earth’s orbit at 7.5 Earth, Moon distances.
During one of its last approaches to work. This 3.6 mile wide block of rock, showered our planet with small meteors.
Since the asteroid often passes by the sun. Its surface is most likely to look like the dry bottom of a month. It’s covered in scales and cracks as it flies past Earth.
These scales break off and cause meteor showers, but the largest potentially hazardous asteroid is the 1999 jamuns.
It’s about the size of 77 soccer fields, it passes by Earth at nine lunar distances, its closest approach to our planet will happen in August 2137 If such a meteorite were to hit an entire continent could be wiped down the rest of the world would experience massive tsunamis, but what survived the event.
So natural scientists are thinking of ways to protect the planet from such a disaster.
The first solution is a controlled Big Bang. One of the laws of physics says that if you apply some force in one direction, it’ll cause a reaction in the opposite direction.
So if we spot an asteroid that is about to collide with Earth, we’ll need to send a rocket toward it. This way will produce a controlled explosion, not inside, but right above its surface.
The blast will be directed upwards in the asteroid will shift downwards. Even this tiny shift would be enough to change the trajectory of the asteroid, and then it’ll fly pastor.
Another way is to send a heavy object, like a spaceship toward the spaceport. Every heavy object has its own gravity.
So, the spacecraft will have to fly close to the asteroid, which will attract the ship to its surface for the engines of the spacecraft will resist the ship will start pulling the asteroid in the opposite direction.
This will change the trajectory of the asteroid and our planet will remain intact.
We can also when the asteroid with the spaceship. We could build a space station, like the ISS, it would be equipped with a bunch of huge magnifying lenses, we would send the station closer to the sun and start looking for potentially hazardous asteroids.
Then we point all the lenses so that the sun’s rays would focus on the giant rock.
The heat would begin to vaporise the matter from the asteroid surface. That’s where physics would come into play. The matter would evaporate humbled in the asteroid would move down.
We can also wrap the asteroid in a reflective film something like usually space bodies absorb most of the sun’s rays, but at the asteroid was covered in oil rays would bounce off its surface.
This would create a weak pushing force. That should be enough to avoid the collision. Of course we can attach rocket engines to the asteroid.
This way, we wouldn’t be able to not only change its trajectory, but also control, but that would depend on the size of the asteroid, and the number of engines in them, we could use this massive rock to women into other larger asteroids.
