Summary
| Description |
English: Main-belt asteroid 55246 Donaldjohanson photographed by the Hubble Space Telescope's (HST) Wide Field Camera 3 (WFC3) on 9 January 2021 at 10:28 UTC. This is a single 60-second exposure image taken with the WFC3's F438W (visible light) filter, imagename IEHT51OHQ.
The asteroid was 1.172 AU away from the HST at the time of observation (as calculated by JPL Horizons). WFC3's pixel scale resolution is 40 milliarcseconds/pixel, corresponding to a physical resolution of 34 km/pixel in this image. The asteroid itself is under 4 km in diameter, so it is not resolved in this image. This image was taken for Keith S. Noll's HST observing program (ID 16452), titled "Is the Lucy Mission Target (52246) Donaldjohanson a Binary?". |
