Vesta – HST – 194° Longitude
About the Object
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.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).
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.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.

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.
This image is a composite 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)
