Olympus Mons - Mars Volcano Mountain and Rheasilvia on 4Vesta
Did you know that Olympus Mons is the tallest mountain in our solar system. It is 2-1/2 times higher than Mount Everest is above sea level and has a height of over 72,000 feet. It is tied with Rheasilvia on the asteroid 4 Vesta as the tallest mountain currently discovered in the Solar System. (Rheasilvia is a crater and was likely created by an asteroid impact which has a central peak that rises 14 miles above the lowest measured part of the crater floor and the highest measured part of the crater rim is 19 miles above the crater floor low point).

HONOLULU (HawaiiNewsNow) 1 - The Subaru Telescope on Mauna Kea captured video last week of a mysterious light over Hawaii. And it wasn’t a bird, plane … or UFO. Turns out the so-called “flying spiral” is actually a new satellite that was launched earlier that day by SpaceX. SpaceX sent a Global Positioning Satellite into space for the U.S. Space Force on Wednesday. On Jan 18, 2023 (HST), the Subaru-Asahi Star Camera captured a mysterious flying spiral over Maunakea, Hawai`i.
