Pluto at opposition

Mars passes less than 2 degrees north of the bright star Spica, Alpha Virginis. Look for the pair about an hour after sunset.

Mercury will be low in the dawn sky all month. This is not a very good apparition of Mercury, though being close to Venus will help you to find it. This is the view half an hour before sunrise in the Northern Hemisphere.

Venus is low in the eastern sky, rising just before the Sun.

Mars is now fading rapidly in brightness as it moves towards the far side of the Sun.

Neptune is in Aquarius all month, rising in the late evening.
