SUMMARY: Ancient people knew of 5 planets: Mercury, Venus, Mars, Jupiter and Saturn. Without our current light pollution, it's amazing they didn't notice Uranus as well - it's possible to see without a telescope. Once telescopes were invented; however, Uranus was discovered, but confused with as a star for a hundred years. It finally took William Herschel to realize in 1781 that the pale blue dot was actually another planet. From April 17-19th, Uranus will visible in the morning sky, less than one degree away from Venus.

I wonder if the future will be revised to show the ancients did indeed know Uranus. I am thinking about how the Piri Ries map now is accredited to the discovery voyages of the Chinese admirals of 1421 so I am not so sure that there may not be a rivision of just exactly what they did know about Uranus.

Hi!
So at the time of Voyager´s flyby Uranus seems to have had some haze above its cloud bands. Now they see more weather there!

One reason why I really like HNSKY. The screen capture shows a close up of Uranus at 6 AM today. The four dots around Uranus are moons, from left to right, Umbriel, Ariel, Titania, and Oberon. They range from magnitude 13.7 to 14.9.

It'll be nice when Uranus is relatively high in the sky during the wee hours of July. Observing the Uranian system will be like a midsummer night's dream.
