Near-Earth asteroid QE2 and its moon, which safely completed a fly-by of our planet on May 31, is featured in a new video footage released by NASA scientists over the weekend.
An asteroid approximately the same size as a small truck passed within 65,000 miles of Earth on Friday night/early Saturday morning, officials from NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California have revealed.
Asteroid 1998 QE2 and its recently discovered moon sailed safely past the Earth on Friday, passing within 3.6 million miles of our planet at approximately 5pm Eastern time, according to various media reports.
Using the orbiting Wide-field Infrared Survey Explorer (WISE), NASA scientists have been able to identify and categorize 28 new asteroid families found in the main belt between Mars and Jupiter.
Strengthening Europe’s contribution to the global hunt for asteroids and other natural objects that may strike Earth, the European Space Agency (ESA) inaugurated the NEO Coordination Center this week.
The Slooh Space Camera is planning to broadcast the fiery asteroid explosion that took place on the moon just a few months ago.
The potential of a human mission to Mars has captured the imagination of many recently. However, before astronauts set foot on the Red Planet, NASA first plans to visit Near-Earth asteroids and potentially to the moons of Mars.
On May 31, a 1.7-mile-wide asteroid called QE2 will hurtle past Earth at a distance of 3.6 million miles. While that distance is far enough for the asteroid to be considered non-threatening, it is close enough to excite NASA astronomers.
Scientists around the world are meeting in Spain this week to talk about the threats that asteroids pose to Earth.
Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less Î”V (change in velocity) than the Moon. In the United States, NASA...
Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less Î”V than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...
