Asteroid Vesta

Similarity between Moon and asteroid Vesta

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).

Didymos Asteroid

Two New Spacecrafts for Impacting Didymos Asteroid

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.

Asteroid 2013 EC

The Asteroid 2013 EC will fly near the Earth on March 4

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

Asteroid Toutatis Getting Closer to the Earth on 12 Dec 2012

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.

Asteroid Apophis

Asteroid Apophis or Apoph is Getting Closer to the 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.

Asteroid Vesta

Variegated Surface of Asteroid Vesta

A new video from a NASA spacecraft shows the huge asteroid Vesta’s complex surface in dazzling and colorful detail. The video drapes high-resolution false color images snapped by NASA’s Dawn probe over a 3-D model of Vesta constructed from the spacecraft’s observations. This visualization enables a detailed view of the variation in the material properties of Vesta in the context of its topography.

Asteroid 2012 KP24

Two Asteroids Zipped Close by Earth

Two small asteroids zipped close by Earth in back-to-back flybys of the planet on May 28 and on May 29. As said NASA scientists while both space rocks came well within the moon’s orbit, they posed no danger to our plane. The newfound asteroid 2012 KP24, which measures approximately 69 feet (21 meters) across, zoomed by Earth on May 28, coming within 32,000 miles (51,000 kilometers) on its closest approach, according to astronomers at NASA’s Asteroid Watch at the agency’s Jet Propulsion Laboratory in Pasadena, Calif.

Asteroid 1999 RQ36

Asteroid 1999 RQ36 Nudged by Sunlight

Scientists on NASA’s asteroid sample return mission, Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx), have measured the orbit of their destination asteroid, 1999 RQ36, with such accuracy they were able to directly measure the drift resulting from a subtle but important force called the Yarkovsky effect the slight push created when the asteroid absorbs sunlight and re-emits that energy as heat.

Near Earth Asteroids

Potentially Hazardous Asteroids

Observations from NASA’s Wide-field Infrared Survey Explorer (WISE) have led to the best assessment yet of our solar system’s population of potentially hazardous asteroids. The results reveal new information about their total numbers, origins and the possible dangers they may pose. Potentially hazardous asteroids, or PHAs, are a subset of the larger group of near-Earth asteroids. The PHAs have the closest orbits to Earth’s, coming within five million miles (about eight million kilometers), and they are big enough to survive passing through Earth’s atmosphere and cause damage on a regional, or greater, scale.
