The Galileo spacecraft flew past 951 Gaspra on the 29th of October 1991. This event marked the first time any human-made object approached an asteroid closely.
Measurements show 951 Gaspra has a surface area of approximately 525 square kilometers. This total area equals the size of Guam or half the land mass of Hong Kong.
951 Gaspra completes one full revolution every 3.29 years while orbiting at an average distance of about 2.21 astronomical units.
Impact craters in such weak gravity take on lopsided shapes that mimic natural facets because ejected fragments from impacts easily fly away into space rather than settling back down.
