For the second time this year, the five brightest planets can be seen at the same time. You can catch them by looking towards the western sky after sunset. The planets will form a line rising up from the horizon.
Mercury and Venus are low to the west, with bright Jupiter shining just above. Higher up in the northwestern sky is Saturn, and completing the set of five is the red planet Mars, high overhead.
Tonight, a beautiful crescent Moon sits just to the right of Jupiter. Keep watching the planets night after night and you can track the progression of the Moon.
As the Moon zips around Earth each month, its apparent motion in the sky is much faster than the more leisurely motion of the planets in their orbits around the Sun.
By Monday, October 15, the Moon will have moved higher in the sky to sit near Saturn, and a few days later, on October 18, the Moon will partner with Mars.
That will also be a perfect evening to see the planets, as Venus and Mercury will be sitting side by side. Of all the five planets, Mercury is the faintest and therefore hardest to see, so having bright Venus as a signpost to Mercury is always an advantage.
In about a week’s time, Venus, which has been the bright evening star for most of this year, will move into the glare of the Sun and out of the night sky.
