New asteroid 2018 LA has been detected on June 2, which was “determined to be on a collision course with Earth, with impact just hours away.” The asteroid 2018 LA is supposed to be only 6 feet (2 meters) across, which is considered very small. The new asteroid was first found by the NASA-funded Catalina Sky Survey, that is situated near Tucson and operated by the University of Arizona.
Ceres is considered as the first asteroid that was discovered in 1801. It is sometimes assumed that Ceres has been reclassified as a dwarf planet, and that it is therefore no longer considered an asteroid. For example, a news update at Space.com spoke of “Pallas, the largest asteroid, and Ceres, the dwarf planet formerly classified as an asteroid”, whereas an IAU question-and-answer posting states, “Ceres is the largest asteroid”. So, according at the point of view of Space.com Ceres is a dwarf planet that is considered as the smallest and closest one.
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.
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.
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.
Astronomers discovered the asteroids and the comets, which are approaching to Earth, the number of objects reached 10 thousand. The asteroid 2013 MZ5 with a diameter about 300 meters was found on June 18 by Pan-STARRS-1 telescope. By the words of Lindley Johnson (the director of NASA division of research of object approaching to the Earth) the detection of 10 thousand objects approaching with Earth is an important boundary. But it is necessary to find still in 10 times more before they can be sure that they won’t pass any, capable to face Earth and to do essential harm to her inhabitants. Objects approaching with Earth (NEO — Near-Earth objects) is the asteroids and comets which can approach to Earth closer, than on 45 million kilometers. Biggest of the asteroids is (1036) Ganymede asteroid, 41 kilometer in size in the diameter. Among 10 thousand found objects about 10% more than 1 kilometer.
The big asteroid, which flew by Earth last month, belongs to new category of space stones. On May 31 asteroid 1998 QE2 and its moon flew by in 3600000 miles (5800000 km) from Earth thanks to what it became the most approximate with our planet during in the next two centuries. The new radar images made by Arecibo radio telescope in Puerto Rico revealed that it is a unique binary asteroid. 1998 QE2 asteroid is dark, red, and primitive that is it doesn’t heat up or melts so as far as other asteroids. 1998 QE2 asteroid isn’t similar to one asteroid, which the scientists observed. This is absolutely new animal in a menagerie of the asteroids approaching with Earth. 305 meters Arecibo radio telescope and 70 m the antenna of a network of long-distance space communication of NASA traced 1998 QE2 asteroid as it came nearer to Earth last month.
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.
