- Jan 26, 2012Uranus can be seen by the naked eye if you know exactly where to look and the skies are dark enough. The threshold for human vision is about magnitude 6.5. Uranus has a magnitude between 5 and 6 (lower numbers are brighter). The problem is that if you don't know where to look, it looks just like a dim star.
Similarly, Venus and Jupiter are visible during the daytime if you know where to look.
Having said that, you're unlikely to be able to spot Uranus after simply looking at a chart on an iphone. Especially if you're in the city. It's simply too dim.

Looks like both Uranus and Venus are close to the moon tonight, with Jupiter just above them. (at least, that's what my iPhone app says!)NathanielGB2BOn Thu, Jan 26, 2012 at 8:24 PM, softscienceofficer <edgeanderson@...> wrote:
There is an incredibly bright celestial object to the left of the moon tonight. It seems too bright for Jupiter or Venus. Is it either of those or the ISS?
