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).
The scientists from Europe and United States have plans to smash a spacecraft for discovering the space rock of huge asteroid nearby in 2022. AIDA plans to send two new spacecrafts to the Didymos asteroid. The scientists think that the Didymos has no chance to impact the Earth, which is a greatest target of this mission. Didymos asteroid is a double asteroid system, which includes two separate space rocks. The main asteroid has huge dimensions- approximately 2625 feet. It is orbited by a small orbit approximately 490 feet. The Didymos asteroid setup is a big target for scientists, as it will allow them to look a binary rock system for the first time. Also, this will give the chance to scientists to deflect the dangerous asteroids, which can impact the Earth.
The asteroid 2013 EC with dimensions from 15 up to 17 meters was founded in Pan-STARRS 1 observatory in Hawaiian Islands on March 1. The center of minor planets appropriated to a new asteroid designation 2013 EC. The asteroid, similar to asteroid fallen in the district of Chelyabinsk, will fly near the Earth on March 4, 2013 at 07:35 UTC. The distance between the Earth and the asteroid will be 362 thousand kilometers, this slightly less than a distance from Earth to the Moon.
Asteroid Toutatis which was discovered on January 4, 1989 by Christian Poll must once again get close to the Earth on December 12. The small asteroid, consisting of two parts of 4.6 km and 2.4 km can not harm our planet. Asteroid Toutatis 4179 was named after the Celtic god. This asteroid has an irregular form, and belongs to the category of Apollo. Asteroid Toutatis has diameter 5.4 kilometers, and the rotation period is 176 hours. At the closest distance the asteroid approached the Earth in 2004. This year, the asteroid must pass by our planet at a distance of 6.9 million kilometers from Earth.
Apophis previously known as 2004 MN4, a member of the Aten group of near-Earth asteroids which had been estimated by NASA as having a 1 in 5500 chance of striking the Earth in 2029. Concealing the energy of 65,000 atomic bombs asteroid Apophis with a mass of 50 million tonnes and a diameter of 320 meters will cross the orbit of the moon and rush to the Earth with a speed of 45 thousand miles per hour. In a collision of Apophis might do unseen troubles.
