The #solarsystem is full of dirty little ice balls. They may become brightly visible as they approach our #sun, leaving behind tails of gas and dust. The word #comet comes from the Greek komētēs, meaning "long hair." Chinese uses 彗星 (huì xīng), meaning "broom star." Indeed, ancient Chinese #astronomers recorded the direction that the broom handle pointed in order to describe such phenomena.

Any other #language roots for comet?

The density of water is 1000kg/m^3. Overall, #Saturn is less dense at 773kg/m^3. Therefore, it is often said that if you could put said #planet into a giant bathtub of #water, it would float. Sounds reasonable.
But for those of us who LOVE to overthink things, here's a fun article where they've done the overthinking for you! (#Spoiler: Saturn WON'T float).

In 1965, #astronauts Wally Schirra and Thomas Stafford played the first musical #instruments in space while aboard Gemini 6. The #harmonica and bells were used to play "Jingle Bells" as part of a festive joke, while both #Gemini 6&7 crews reported spotting #Santa from orbit (both missions were in orbit simultaneously to test perform a rendezvous).
