Mars continues to add its ruby-red glow to the constellation Taurus the Bull this week.
Shining at magnitude 1.6, the Red Planet appears slightly fainter than the constellation’s brightest star, ruddy 1st-magnitude Aldebaran. The planet lies about 25° above the western horizon an hour after sundown and doesn’t set until after 11 p.m. local daylight time.
Once the sky darkens, you should notice that Mars is perched within the borders of the 6th-magnitude open star cluster NGC 1746. Because the cluster is big — its diameter is slightly larger than the Full Moon — you’ll want to use binoculars or a telescope at low power for the best views.
Unfortunately, Mars spans only 4″ and won’t show any detail.
