Venus, Mars, and Regulus come together on July 9th

Trine of Venus, Mars and Regulus

Venus is the brightest point of light in the night sky. At the beginning of July, it will set in the west less than two hours after sunset. When you look towards the fading colors of the sunset, Venus will be the first light you see. The closest planet to Earth shines at -4.7 magnitude in the first half of the month. On July 9, 2023, if you wait until the sky gets darker, you will spot two points of light very close together and above the bright planet Venus. The brightest and whitest light is Regulus, the brightest star in Leo Leo. Next to it is red Mars. These two worlds appear to be little more than a moon’s width apart from each other on July 9 and 10.

To get a better look at this trio, try focusing on them with binoculars. Through binoculars, you may be able to see the crescent phase of Venus. Next, find the white and red points of light close together in the same field of view. These are Regulus and Mars, respectively.

Mars should be a steady light, but Regulus might twinkle. That’s because Mars is closer to Earth. A star – like Regulus – so far away, nothing more than a prick of light in our sky. So the undulating Earth’s atmosphere through which we stare can make the point of Regulus jump, while the disc-like Mars remains stationary.

Bottom line: You can see Venus, Mars, and Regulus close together on July 9 and 10. Use binoculars to get a better view of the faint objects, separated by a distance of just over the width of the moon.
