VLT Measures Main-Belt Asteroid Euphrosyne and Its Moon

Using the high-angular resolution observations from ESO’s Very Large Telescope (VLT), astronomers have determined the 3D shape, diameter and density...

The asteroid 31 Euphrosyne glides across a field of background stars in this time-lapse view from NASA’s WISE spacecraft. WISE obtained the images used to create this view over a period of about a day around May 17, 2010, during which it observed the asteroid four times. The moving asteroid appears as a string of orange dots because it is much cooler than the distant background stars. Stars have temperatures in the thousands of degrees, but the asteroid is cooler than room temperature. Thus the stars are represented by shorter wavelength blue colors in this view, while the asteroid is shown in longer wavelength reddish colors. Image credit: NASA / JPL-Caltech.
