What would happen if Apophis hit Earth?
What would happen if Apophis hit Earth? Apophis would cause widespread destruction up to several hundred of kilometers from its impact site. The energy released would be equal more than 1,000 megatons of TNT, or tens to hundreds of nuclear weapons.
Will Apophis ever hit Earth?
Even though the asteroid Apophis won’t hit Earth for at least another century, its scientific impact will be tremendous. Jump to: Background. Apophis will not hit Earth.

Will Apophis hit the Earth in 2029?
Yes. Apophis will still pass by the Earth in 2029 – specifically on April 13 – at a distance less than 20,000 miles (32,000 kilometers) from the Earth’s surface.
What country will Apophis hit?
During that 2029 close approach, Apophis will be visible to observers on the ground in the Eastern Hemisphere of Earth, which includes Asia, Africa and parts of Europe.
What is Apophis the god of?
Apep (also spelled Apepi or Aapep) or Apophis (/əˈpoʊfɪs/; Ancient Greek: Ἄποφις) was the ancient Egyptian deity who embodied chaos (ı͗zft in Egyptian) and was thus the opponent of light and Ma’at (order/truth). He appears in art as a giant serpent.
How big was the meteor that killed the dinosaurs?
about 7.5 miles
The asteroid was about 7.5 miles (12 kilometers) in diameter and was traveling about 27,000 mph (43,000 km/h) when it created a 124-mile-wide (200 km) scar on the planet’s surface, said Sean Gulick, a research professor at the University of Texas Institute for Geophysics, who led the study.
Can Apophis cause extinction?
Many of the smaller objects break up when they reach the Earth’s atmosphere and have no impact. However, a NEO larger than 1km [wide] will collide with Earth every few hundred thousand years and a NEO larger than 6km, which could cause mass extinction, will collide with Earth every hundred million years.
What would happen if Ceres hit Earth?
The Himalayan mountains are completely destroyed in the fiery fallout. Asteroid Ceres is an enormous 296 miles (476 km) across, meaning if Earth were the size of a 1p coin, the space rock would be about the size of a seed.
How fast is Apophis traveling?
NASA’s Near Earth Object Program (http://neo.jpl.nasa.gov) offers characteristics of Apophis to use in the calculations: diameter of 320 meters, density of 2,600 kilograms per cubic meter, and speed of 12.6 km per second.
Where is the asteroid Apophis now?
Asteroid 99942 Apophis is currently in the constellation of Aquarius.
Is the earth going to be destroyed in 2036?
In a recent report, American space agency NASA has revealed that planet earth may actually face massive destruction in the year of 2036, by an asteroid strike. According to NASA, the asteroid named Apophis will collide with Earth and it will have result in human extinction.
How big is the asteroid coming in 2029?
With a diameter of about 340 metres (1,115 feet), Apophis – named after the ancient Egyptian god of chaos – was described by Nasa as “one of the most hazardous asteroids that could impact Earth” after astronomers at a US observatory detected its existence in 2004.
What NASA says about Apophis?
NASA Says Asteroid Apophis Isn’t A Risk To Earth For 100 More Years The asteroid Apophis was taken off of NASA’s “risk list” after the space agency determined earlier this month that it poses no risk of impact to Earth within the next century.
What if Apophis hits us in 2029?
How far is Apophis from Earth right now?
On the night of March 5, 2021, the huge space rock will pass at 10,471,577 miles (16,852,369 km) from our planet, i.e. about 44 times the distance to the moon. Apophis is then expected to reach a visual magnitude of 15 to 16. This is too faint to be seen in small telescopes.
Will asteroid 99942 Apophis eclipse the moon when it passes by?
Wouldn’t an object that big and close be able to eclipse the Moon, if it should pass in front of it? On Friday the 13th in April 2029, a 1,000-foot-wide asteroid named Apophis will pass close enough to Earth (within 20,000 miles) to briefly appear as a 3rd-magnitude star in the night sky.
