Walkabout the Galaxy
Ryugu, Bennu, Ultima Thule, Oumuamua
Astrophysics and Astronomy | Physics
In our first letter-themed episode, the Astroquarks check in with Ryugu, Bennu, Ultima Thule, and Oumuamua, while Jim contemplates muumuus. We also talk about dynamically trapped dust clouds near the Earth to make Addie happy, and we have a truly embarrassing sponsor. We're sincerely sorry, but you'll enjoy all the U's, from asteroids, to missions to a U-themed trivia. We do it all for you!
Uranus is big and blue, and colder than you might expect. Uranus has several narrow rings around it. Uranus is filled with a lot of methane gas, and wind at Uranus blows as fast as 900 km/hour! Uranus has an unusual tilt that is probably due to something smashing into Uranus a long time ago. But Uranus is more than just the butt of astronomy jokes. The seventh planet from the solar system has at least 27 moons which are named after characters from Shakespeare and Alexander Pope. Its moon Miranda, though tiny, has world-encompassing grooves and giant cliffs suggesting it may have been broken up and reaccreted in its past. So don't forget to check your Uranus before you head out of the solar system on your walkabout the galaxy.
