SOLAR SYSTEM

Detailed explanation-1: -The only entry of a large meteoroid into Earth’s atmosphere in modern history with firsthand accounts was the Tunguska event of 1908. This meteor struck a remote part of Siberia in Russia, but didn’t quite make it to the ground. Instead, it exploded in the air a few miles up.

Detailed explanation-2: -The asteroid 2023 DZ2 will pass at a distance of over 100, 000 miles, less than half the distance between the Earth and the moon. It’s about 160 feet long-about the size of an airliner. An asteroid that size could cause significant damage if it hit a populated area, hence its nickname.

Detailed explanation-3: -A massive 150-foot asteroid called ‘2023 FZ3’, which is as big as an aeroplane, is estimated to come close to Earth on April 6. The asteroid is moving towards Earth at a speed of 67656 kmph and will closely approach the planet at a distance of 4, 190, 000 km.

Detailed explanation-4: -"Planet killer” asteroids are space rocks that are big enough to cause a global mass extinction event, through the chucking up of dust into the upper atmosphere and the blotting out of the sun’s light, if they were to smash into Earth.

Detailed explanation-5: -This was the largest such event to occur during the time when humans were known to be on Earth and evolving (as they always are). Researchers say the event gives us clues as to whether modern humans could survive a dinosaur-size cataclysm today. The answer is yes, but it would be difficult.

Detailed explanation-6: -So now we have the answer: For two people to see the same meteor, they can be no more than 2 x 1, 120 = 2, 240 kilometers apart. As an example, that’s pretty close to the distance between Washington, DC and Denver.
