Ceres. Image taken by NASA's Dawn spacecraft of the dwarf planet on Feb. 19 from a distance of nearly 29,000 miles (46,000 km). It shows that the brightest spot on Ceres has a dimmer companion, which apparently lies in the same basin. (Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

Geminids 2014. Taken from the summit of Mt. Changbai as a composite of digital frames capturing bright meteors near the shower's peak. Orion is near picture center above the volcanic cater lake. The shower's radiant in the constellation Gemini is to the upper left. The photographer encountered severe wind gusts and minus 34 degree C temperatures near the summit.

Geminids 2014. View from mid-southern latitudes at about 11:00 p.m. local time around December 13. The graphic doesn't represent the view at the time of maximum, it's just meant to help observers find the radiant location. The red line across the bottom of the image represents the horizon. Although the actual radiant is below the horizon, the stars just above the horizon are those of the constellation Perseus. (Image produced by Gary W. Kronkr using SkyChart III and Adobe Photoshop.)

Geminids 2014. View from mid-northern latitudes at about 9:00 p.m. local time around December 13. The graphic doesn't represent the view at the time of maximum, but is just meant to help prospective observers find the radiant location. The red line across the bottom of the image represents the horizon. (Image produced by Gary W. Kronk using SkyChart III and Adobe Photoshop.)

Spitzer Space Telescope Views Collision Between Large Asteroids August 29, 2014 NASA’s Spitzer Space Telescope witnessed a giant surge in dust around the star, likely the result of two asteroids colliding. Image Credit: NASA/JPL-Caltech

Jure Atanackov captured this brilliant -9 magnitude Perseid fireball in constellation Cetus on August 12, 2010.

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.

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.
