What happens if Apophis hits the 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.
Which country will Apophis hit?
That is about one-tenth of the distance between the Earth and the Moon. 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 will happen in 2042?
By 2042, the Uranus mission is well underway, revealing a wealth of new scientific data about its atmosphere, interior, rings and satellites. The planet is globally surveyed with unprecedented detail; its dozens of moons are imaged in stunning resolution, while new moons are discovered too.

What is the size of the Apophis asteroid?
99942 Apophis (/ ə ˈ p ɒ f ɪ s /) is a near-Earth asteroid with a diameter of 370 metres (1,210 feet) that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
How far away is Apophis from Earth?
At its farthest, Apophis can reach a distance of about 2 astronomical units (One astronomical unit, abbreviated as AU, is the distance from the Sun to Earth.) away from Earth. It’s expected to safely pass close to Earth — within 19,794 miles (31,860 kilometers) from our planet’s surface — on April 13, 2029.
What will we learn from Apophis in 2029?
The most important observations of Apophis will come during its close Earth flyby in 2029. Scientists around the world will study the asteroid’s size, shape, composition and possibly even its interior. Apophis is a 1,120-foot-wide (340-meter-wide) asteroid.
