Hi everyone.
I'm creating this thread for discussing all types of planets, including Exoplanets, Rogue Planets, Major, Dwarf* & Minor Planets, and Moons.
*This IAU term is total nonsense.
Today from 12:12 to 17:42, the Transit of Mercury is visible from the UK, a solar filter is needed on all binocular and telescope viewings to be safe for the eyes. Magnification is needed to view the event which won't occur again for 3 years. An alternative way of viewing uses cardboard, but I've always disliked that method.
Mercury Facts:
1, it's smaller than Ganymede, Jupiter's biggest moon.
2, it's typically varies from +400 to -170 degrees Celsius.
3, there's a outward dent on one side of the planet caused by an impact crater on the opposite side.
4, it was once thought there was a planet Vulcan even closer to the Sun than Mercury, this has no current evidence.
Also in the news, a small red dwarf star, Trappist-1 which is just 40 light years away, has 3 potentially habitable M-Class planets, the first such discovery from such a dim star.
Anyone else has planet info or news they'd like to talk about?
