There are millions of asteroids from which some of them is dangerous uniquely. A potentially hazardous object (PHO) is a near-Earth object with an orbit that has the potential to make exceptionally close approaches to the Earth. It is also of a size large enough to cause significant regional damage in the event of impact. Astronomers indicate that between 37,000 and 78,000 tons of solar system debris hit Earth each single year. Fortunately, they usually rain down in tiny pieces that burn up in the atmosphere. Now, we’d like to call you attention introducing top 10 dangerous asteroids.
The Psyche mission is a journey to an exclusive metal asteroid orbiting the Sun between Mars and Jupiter. NASA explains what makes the asteroid Psyche exclusive and unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system. The Psyche mission is going to leave Earth in 2022. Although the original plan was supposed to launch in 2023, NASA has changed the timeline and is expected to start its mission in 2022. Observations from Earth hint that the 124-mile-wide (200 kilometers) world is 95 percent metal, just like the core of a rocky planet.
What do you think are there aliens living on the cigar-shaped asteroid Oumuamua? To find out the astronomers in the outback of Western Australia used the Murchison Widefield Array telescope to eavesdrop on the rocky visitor. They found out “We found no such signals with non-terrestrial origins,” the researchers wrote in the paper. Scientists learned about the mysterious, reddish space rock last year when it was spotted by the Pan-STARRS1 telescope in Hawaii in October.
NASA Hammer spacecraft is going to save our lives. Asteroid Bennu has a 1 in 2,700 chance of hitting Earth the 21th of September in 2135. But don’t worry NASA has a plan to destroy it using nuclear bombs before it reaches here. The chances of Bennu actually making contact with Earth is highly unlikely, but the US government wants to make sure that this threat is neutralized. Bennu is currently about 54 million miles from Earth and orbits Sun.
The US space agency said “The space rock will shave safely by Earth at around 5:30 pm”. It will remain about 39,000 miles (64,000 kilometers) from Earth, which is less than one-fifth the distance to the Moon.“Asteroids of this size do not often approach this close to our planet — maybe only once or twice a year” : said Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory. According to the NASA an asteroid bigger than a city bus is on track to zoom by Earth Friday at a safe but close distance, less than one-fifth as far away as the Moon. The asteroid is estimated to be between 50 and 130 feet (15 and 40 meters) in size.
Astronomers from NASA says that asteroid 2014 RC will pass extremely close to Earth on September 7 . Asteroid 2014 RC discovered just days ago on August 31 by the Catalina Sky Survey near Tucson, Arizona, and independently detected the next night by the Pan-STARRS 1 telescope, located on the summit of Haleakalā on Maui, Hawaii. Astronomers estimate that the asteroid is about 60 feet (20 meters) in size. Its close pass, 2014 RC will be about 21,126 miles (34,000 km) from Earth’s surface. That’s about 10 times closer to the Earth than the moon.
The small comet P/2010 A2 (LINEAR) has characteristics at the same time an asteroid and a comet. For the first time this asteroid was open on January 6, 2010. When this asteroid was in the main asteroid belt, astronomers noticed at it a tail, as at a comet. For this reason initially this asteroid was entered in the catalog as a comet of the main asteroid belt.
About 1 month astronomers observed the object P/2010 A2 (LINEAR) with help of Hubble telescope. After one month the astronomers came to conclusion that it is not a comet with a tail from parts of ice, but an asteroid with a tail from a dust and the gas, formed after collision with any other space object.
The asteroid 1999 RQ36 by the results of competition among school students received a new name Bennu, in honor of an Ancient Egyptian deity heron. The asteroid (101955) 1999 RQ36 of 500 meters in size opened by scientists from the LINEAR project of Massachusetts Institute of Technology. In 2182 it will approach to the Earth. After “cancellation” of threat of Apofis and some other asteroids, it became the main potentially dangerous object for the Earth. Participants of the OSIRIS-REx project, for receive a name, which will be easier to be said, than 1999 RQ36, declared competition on the best name, which participants could become school students from any country of the world, but more younger than 18 years. On competition arrived more than 8 thousand options from school students from 25 countries. As a result the Committee on names of small bodies of Solar system of the International astronomical union accepted the option offered by nine-year-old Michael Puzio from Northern Carolina. The American asteroid project OSIRIS-REx for the USA will be the first program of research of an asteroid with help of an automatic probe.
Scientists from NASA’s Lunar Science Institute considered that essential changes of Jupiter’s orbits and other gas giants could destabilize separate parts of a belt of asteroids about 4 billion years ago. This change started bombing, which created many craters on the Moon. The Moon and large bodies of the main belt of asteroids, including asteroid Vesta, despite the distance dividing them, suffered from the same “bombing”. The scientists compared results of research of samples of the lunar soil and meteorites called clan of HED (It is assumed that these meteorites got to Earth from the asteroid Vesta).
