Asteroid 243 Ida & Dactyl. (August 28, 1993) The second asteroid to be visited and the first found to have its own tiny moon. (Image: Galileo)

Images Of Asteroids Ida & Dactyl

The Geminid meteor shower is one of the year’s best, peaking in December. The Boulder Flatirons (Colorado) are in the foreground. (Image credit: Patrick Cullis) Jupiter is the bright “star” in the center, and you can also see the Pleiades star cluster near it with Orion on the left.

Which of These Photos Will Win the RGO Astrophoto of the Year?

Willamette Meteorite. It weighs some 32,000 pounds. You can get an idea of its size from the two people in the picture. The meteorite is located in the Rose Center of the American Natural History Museum in New York City. (Photo: GreenGimmick, Photobucket)

The light curve of UCAC4 248-108672 during Chariklo’s occultation on 3 June 2013. The light curve shows the stellar light as a function of time, with the central dip caused by Chariklo transiting in front of the background star, and the two dips either side due to Chariklo’s two rings blocking some of the stellar light.

Multiple frame picture of a meteoroid falling. Taken from the helmet camera of a Norwegian skydiver who was narrowly missed by the space rock. Coming so close to April 1st, it sounds like a slightly belated April Fool. However experts have examined video footage and agree that what they see is consistent with a meteoroid.

Asteroid Ida and its satellite Dactyl. Image made from data collected by the spacecraft Galileo on its close approach to the asteroid (1993-08-28).

Chariklo is a comet-like miniature planet located between Saturn and Uranus. It has a diameter of 250 km and new observations show that there are two rings of ice particles and pebbles. This is the first time such a small celestial body with rings has been observed. (Credit: Lucie Maquet)

Artist's impression of the asteroid belt. (Image credit - or blame! - NASA/JPL-Caltech) The asteroid belt isn't crowded, even with 800 trillion asteroids bigger than a meter. Its volume is about 50 trillion trillion cubic km, giving each asteroid an average billions of cubic km of space. "In fact," as Brian Koberlein says, “to get even close to an asteroid takes a great deal of effort.” Mona Evans, "Asteroid Facts for Kids" www.bellaonline.c...

Painted Stone: Asteroids in the Sloan Digital Sky Survey on Vimeo (credit: Alex Parker) Animation showing the orbital motions of over 100,000 of the asteroids observed by the Sloan Digital Sky Survey (SDSS). Colors illustrate the different compositions and relative sizes of each asteroid are also illustrated. The average orbital distances of Mercury, Venus, Earth, Mars, and Jupiter are illustrated with rings.

▶ ESA Euronews: Accidents and Asteroids - YouTube. Looking at the power of the Chelyabinsk meteor (which struck a year ago and is visible starting around 1:15 in the video above) is still terrifying all these months later. Happily for those of on Earth worried about these big space rocks, the world’s space agencies are taking the threat seriously and are starting to implement new tracking systems to look out for more threatening space rocks.

The largest recovered piece of the Chelyabinsk meteorite fall from 2013-02-15. It was lifted from the bottom of the Chebarkul Lake and placed on display in a local museum in Chelyabinsk. It weighs about 1,442 lbs. (Credit: Reuters / Andrey Tkachenko)

Perseid meteor and ISS, August 13, 2012. (Photo: Martin Popek) The immediately obvious thing is the star trails, but the horizontal line cutting across the trails is the International Space Station going overhead. There is a bright Perseid on the left hand side of the picture.

"Snowman" on the asteroid Vesta. (2011-08-06) Three craters imaged by NASA's Dawn mission.

Asteroid P/2010 A2, imaged by Rosetta's OSIRIS Narrow Angle Camera. It had a high-speed collision with a small rock, producing a dust trail. On the left the full field of view shows the background star field & nebula, which had to be subtracted to show the dust trail in the righthand close-up of the asteroid.

Perseid radiant. The radiant is the area where the meteors in a shower seem to originate. People in the northern hemisphere get the best view of the Perseids because in the southern hemisphere the radiant is below the horizon. Southern hemisphere observers can still see a worthwhile number of meteors coming up from the horizon. Mona Evans, "Meteor Shower - the Perseids" www.bellaonline.c...

Debris plume of Chelyabinsk meteor. Some of the bits on the ground will go into Olympic medals, but a plume of fine debris went into the atmosphere. In four days the faster, higher part of the plume (red) went all the way around the northern hemisphere and back to Chelyabinsk. It was tracked by instruments on the Suomi NPP satellite for several months. (Image Credit: NASA's Goddard Space Flight Center Scientific Visualization)

Perseids 2013. Beautiful timelapse from P-M Hedén in Sweden, showing 25 Perseid meteors, noctilucent clouds, a faint aurora, airglow, satellites passing over and lightning. “It was a magic night!,” P-M said. Mona Evans, "Meteor Shower - the Perseids", www.bellaonline.c...

Vesta, more than an asteroid. Indeed, almost a planet
