Which space agency has revealed that giant asteroid 99942 Apophis is expected to fly close to Earth in a decade?
A
NASA
B
Roscosmos
C
JAXA
D
CNES
Explanation: 

Detailed explanation-1: -According to NASA, the Asteroid 99942 Apophis will make an extremely close trip to Earth on April 13, 2029. On that day, this space rock will come as close as 38000 kilometers to Earth. This is closer than many geostationary satellites orbiting the planet.

Detailed explanation-2: -Although Apophis will not hit Earth anytime soon, the asteroid will make a close encounter with our planet on April 13, 2029, when it will pass within just 19,000 miles (31,000 kilometers).

Detailed explanation-3: -The asteroid 2022 AP7 is no exception. “Over time, this asteroid will get brighter and brighter in the sky as it starts crossing Earth’s orbit closer and closer to where the Earth actually is,” Dr.

Detailed explanation-4: -On April 13, 2029, Apophis will pass less than 20,000 miles (32,000 kilometers) from our planet’s surface – closer than the distance of geosynchronous satellites. During that 2029 close approach, Apophis will be visible to observers on the ground in the Eastern Hemisphere without the aid of a telescope or binoculars.

Detailed explanation-5: -Not anytime soon. It definitely will miss Earth in 2029 and 2036, and radar observations of Apophis during the asteroid’s flyby in March 2021 ruled out an impact for at least the next 100 years.
