Walkabout the Galaxy
Astrophysics and Astronomy | Physics
That asteroid is rogue, and that's hyperbolic, but not hyperbole. The astroquarks welcome Dr. Dan Durda to discuss the first detection of a planetary object passing through our solar system that definitively came from another planetary system. All those Star Trek episodes where there is a wandering planet or comet or asteroid in space are now officially validated!
If what goes around, comes around, you can thank orbits. A dash of Newtonian gravity and some Keplarian geometry, and before you can say conic section, orbits will have you on your elliptical way, and without all the effort and sweat of that elliptical machine collecting dirty laundry in your bedroom. Orbits are the original energy conserver, carrying comets, dust, asteroids, planets, stars, and more on their way around the cosmos. So whether you're feeling hyperbolic or perfectly round, we've got a shape to fit your mood. Orbits, the best bet for every Walkabout the Galaxy.
