Will Apophis Hit Earth In 2029 Or 2036?
Scientists have long monitored the trajectory of the asteroid Apophis, continually updating its chances of an Earth impact. These calculations have evolved, capturing the attention of both the scientific world and the public. The question remains: Will Apophis simply pass by Earth, or is it a harbinger of a significant event that could alter our planet?
00:00 - Introduction
Named after the Egyptian god of chaos, this 370-meter asteroid, once considered a distant object of no concern, is now recognized for its potential to come alarmingly close to our planet.
00:41 - Can Apophis Hit Earth
Early predictions gave it a 2.7% chance of hitting Earth in 2029, which was quite alarming.
02:24 - Potential Impact Scenarios
If an asteroid like Apophis hit Earth. It could unleash over 1,150 megatons of TNT, way more than the biggest nuclear bomb. If it hit the ocean, it could cause huge tsunamis and destroy coastal cities. A hit on land could wipe out big cities and throw debris into the air, changing the climate and temperature.
04:19 - NASA's Analysis and Observations
NASA's careful studies and constant watch have given us good news: Earth won't be in danger from Asteroid Apophis for at least 100 years. Thanks to advanced radar technology and continuous monitoring, we're now certain of its path.
05:59 - 2029 and 2036 Approach
As Apophis gets closer, it will pass over the Indian Ocean, Africa, and the Atlantic. It will be bright enough to see without telescopes from the Eastern Hemisphere.
People will see Apophis in the sky when it's closest to Earth, about 20,000 miles up. This is a rare chance to see such an event with the naked eye.
06:58 - Possible Asteroid Quakes
The flyby might also cause asteroid quakes—small shakes from Earth's gravity. These could tell us what's inside Apophis and help predict where it will go next.
07:28 - Planetary Defence
Scientists have some ideas and are starting to try them out. The main ways to do this are hitting the asteroid to push it away, using a spacecraft's gravity to pull it off course, or using nuclear blasts to nudge it.
07:59 - Kinetic Impactor Method
It involves crashing a spacecraft into an asteroid on purpose to change its path just a little.
08:30 - Gravity Tractor Method
It's about having a spacecraft fly near an asteroid for a long time. The small gravitational force between them can slowly change the asteroid's path, moving it.
08:51 - Nuclear Deflection
Nuclear deflection is a method used only if all else fails. It doesn't mean destroying the asteroid, as that could break it into dangerous pieces. Rather, a nuclear blast would happen close to the asteroid. The blast's heat and energy would turn part of the asteroid into vapour. This vapour pushes the asteroid onto a different path.
