Worst date: Watching the sunset on Mercury (It only happens every 180 Earth days!) Best date: Spotting Mercury in the night sky on our home planet! Look for it shining brightly, low in the west, starting half an hour after sunset March 21-25 in the Northern Hemisphere!
@NASAGoddard How does Mercury appear so bright in our sky from that distance when it's surface illumination levels are as dark as the Moon?
@NASAGoddard @NASASolarSystem Wait wait wait! So, if it happens every 180 years, how long DOES a sunset last?
@NASAGoddard @NASASolarSystem No more mld dollars to nazi (Z)elensky regime! But to interstellar starships!
@NASAGoddard @NASASolarSystem Wonders of the universe, unfathomable.
@NASAGoddard @NASASolarSystem La façe cachée de la lune ,vraiment est-elle cachée à notre vue ?
