Later this month (night of Sept 9th), Uranus reaches the point in her orbit where she is at opposition to the sun (as seen from Earth), that is Earth & Uranus are closest together. The planet is currently positioned to also show 99.99% of her disc; and she’ll reach equinox early this winter. It is therefore a good time for viewing. I took both of the following images on the night 3rd/4th September ’07.
Exposure 1second @ ISO400 – Canon 20D
Uranus is a gas giant in our outer solar system. Uranus is the seventh planet from the Sun & 3rd largest in our solar system. It is extremely cold (-215C) & is probably more similar in core chemistry to Neptune who lies beyond her, than Jupiter or Saturn who are closer to the us. Uranus’ atmosphere contains clouds of frozen water, ammonia & methane, these give the planet her blue/green appearance.
