Neptune at opposition
2014 Aug 29
Neptune will be well placed for observation, lying in the constellation Aquarius, far above the horizon for much of the night.
Regardless of your location on the Earth, Neptune will reach its highest point in the sky at around midnight local time.
This optimal positioning occurs when Neptune makes its closest approach to the point directly opposite to the Sun in the sky – an event termed opposition, the exact moment of which will be 15:18 BST. Since the Sun reaches its greatest distance below the horizon at midnight, the point opposite to it is highest in the sky at the same time.
