| About The Object | |
|---|---|
| Object Name | Vesta, 4 Vesta |
| Object Description | Asteroid |
| Distance | The semi-major axis of Vesta's orbit about the Sun is 2.36 astronomical units (AU) or roughly 219 million miles (353 million kilometers). |
| Dimensions | Vesta has a mean diameter of approximately 330 miles (530 kilometers). The object has a 354-mile (570-km) diameter at the equator and a slightly smaller diameter of 288-miles (464-km) pole-to-pole. |
| About The Data | |
| Data Description | This image was created from HST data from proposal : J.-Y. Li (University of Maryland, College Park), L. McFadden (NASA/GSFC), P. Thomas (Cornell University), C. Russell (University of California, Los Angeles), M. Mutchler (STScI), and M. Rayman, C. Raymond, and S. Weinstein-Weiss (JPL/Caltech). |
| Instrument | HST>WFC3/UVIS |
| Exposure Dates | February 25 and 28, 2010, Exposure Time: 20 minutes |
| Filters | F373N (373 nm) and F469N (469 nm) |
| About The Image | |
| Color Info | These images are composites of separate exposures made by the WFC3 instrument on the Hubble Space Telescope (HST). Each filter was used to sample a narrow wavelength range. The composite colors result from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Yellow/gold: F469N (469 nm) Cyan: F373N (373 nm) |
