It completes an orbit around the Sun every 436.604 days (1.2 years) and every 6 years comes very close to Earth, within 0.002 AU. DiscoveryĠ:324:35NASA monitoring “potentially hazardous” asteroid – YouTubeYouTube What type is Bennu?ī-type asteroid Bennu is a B-type asteroid with a ~500 meter diameter. On April 12, 2068, the nominal trajectory has Apophis 1.87 AU (280 million km) from Earth….99942 Apophis. Where will the 2029 asteroid hit?Īpophis will make two modestly close approaches to Earth in 2036, but even the planet Venus will come closer to Earth in 2036. A study based on the findings published Wednesday in the journal Icarus. The asteroid, which is being studied by NASA ’s OSIRIS-REx, shows some surprising activity on its surface, and scientists are beginning to understand what might be causing it. If Bennu does impact Earth, it would create a crater between 10 to 20 times its size and cause an area of devastation that could reach 100 times the size of the crater, said Lindley Johnson, NASA's planetary defense officer. How big is Bennu?Ģ62.5 m101955 Bennu / Radius What happens if Bennu hits us? Bennu 101955 is a carbonaceous asteroid in the Apoll. On Tuesday, scientists eager to combat climate change released an open letter in the journal. The date with the highest probability of a collision is September 24, 2182, when Bennu has a 1 in 2,700 (about 0.037%) chance of hitting the Earth. It is the most dangerous asteroid that is listed on the Sentry Risk Table. Thankfully, the probability of Bennu colliding with Earth is small: about a 1 in 1,750 (or 0.057%) chance between now and the year 2300. Asteroid Bennu is assumed to be about 500 meters wide. If it does crash, it may create a crater about 5-10 km wide. Lindley Johnson is NASA's planetary defence officer told VOA that a hit from Bennu would not destroy all life on Earth. New calculations put the odds at 1 in 1,750, a figure slightly higher than previously thought. Recently NASA updated its forecast of the chances that the asteroid Bennu, one of the two most hazardous known objects in our solar system, will hit Earth in the next 300 years. However, newly released observations of 67P suggest that a burst.
What are the chances of Bennu hitting Earth? Initially, scientists assumed that unusual effect came from jets of material within the comet. “An object Bennu's size … would pretty much devastate things up and down the coast.” Bennu is about one-third of a mile (half a kilometer) wide, and if it were to impact Earth, it could cause serious destruction. As a result, scientists behind new research now say they’re confident that the asteroid’s total impact probability through 2300 is just 1 in 1,750.
