Oddly shaped asteroid once considered an impact risk for Earth races past the planet | Space

The asteroid , designated 2011 AG5, passed safely past our planet at a distance of around 1.1 million miles (1.8 million kilometers), about five times the distance between Earth and the moon .

The close approach allowed scientists at NASA's Jet Propulsion Laboratory (JPL) in Southern California to track the space rock, and make invaluable observations to help determine its size, rotation, surface details, and, most notably, shape.

A 500-Meter-Long Asteroid Flew Past Earth, and Astronomers Were Watching - Universe Today

An asteroid the size of the Empire State Building flew past Earth in early February, coming within 1.8 million km (1.1 million miles) of our planet.

"Of the 1,040 near-Earth objects observed by planetary radar to date, this is one of the most elongated we've seen," said Lance Benner, principal scientist at JPL who helped lead the observations, in a JPL press release.

'Potentially hazardous' asteroid that recently zipped past Earth is an elongated weirdo with an ...

Astronomers recently got an up-close look at a "potentially hazardous" asteroid as it whizzed safely past Earth, and what they saw caught them by surprise: The space rock is unusually elongated for an asteroid and is spinning much more slowly than expected. 

The asteroidal anomaly, known as 2011 AG5, was discovered in January 2011 by the Mount Lemmon Survey using a telescope based near Tucson, Arizona.

Asteroid targeted by NASA spacecraft gets marvelous name Dinkinesh | Space

The first asteroid to be visited by NASA's space rock-hopping craft Lucy has finally been given a name.

Dinkinesh was discovered in 1999, but like millions of other main-belt asteroids , it didn't get a name, only receiving a designation number when its orbit was well determined. First known under its provisional designation as 1999 VD57, the asteroid later entered catalogs as 152830.

EarthTalks: Chabot to discuss NASA's Double Asteroid Redirection Test (DART) | Penn State University

DART is the first-ever mission dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid's motion in space through kinetic impact. Credit: NASA . All Rights Reserved .

UNIVERSITY PARK, Pa. — On Sept.

Nancy Chabot, planetary scientist at the Johns Hopkins University Applied Physics Laboratory, will share some of the latest results relating to DART's impact event and discuss what that means for potentially applying this technique, if needed in the future, in her talk "Double Asteroid ...
