September 2nd, 2015
For several months now, there’s been a lack of planets in the sky as Mercury, Venus, Mars and Jupiter have been too close to the Sun for easy observation. Only Saturn has remained, low over the south-western horizon, but even the jewel of the solar system is slowly succumbing to the Sun.
Now, however, the tide is turning in our favor as both Venus and Mars are gradually emerging from the pre-dawn twilight and will be joined by Jupiter later in the month. Venus and Mars will be at their closest in early November, but in the meantime, early risers will have the opportunity to watch these worlds dance.
This is the first of several for September. Come back on the 10th as the pair are joined by the Moon and return on the 24th to see Mars very close to the bright star Regulus.
