You can see Mars, Venus and Mercury near the crescent moon tonight. Here's where to look.
Hopefully the skies in your area are clear tonight (July 19), because there will be an excellent grouping of celestial bodies shortly after sunset.
While smoke from Canadian wildfires continues to create hazy skies in many parts of North America, the moon, Mercury, Venus and Mars are forging ahead with their planned night sky party tonight. Just after sunset, the faintest sliver of a two-day-old crescent moon will be low in the western sky. Joining it will be three of the solar system's inner planets, not far from one another in the sky in the Leo constellation, the Lion.
From New York City, the quartet should appear to the west just as the skies begin to darken at sunset. Note that the three planets and the moon will already be fairly low in the sky by the time it gets dark, so you'll need to have a decent view of the horizon to make the most of this skywatching opportunity.

TOP TELESCOPE PICK:
Looking for a telescope for the solar system planets? We recommend the Celestron Astro Fi 102 as the top pick in our best beginner's telescope guide.
Venus will be the brightest of these four objects and thus will appear first in the evening twilight. Find the moon roughly a fist's width at arm's length to the right of and slightly above Venus.
Go in the opposite direction from Venus — above and to the left — to see the steady glow of red-orange Mars.
Mercury will be far dimmer and more difficult to locate; it will be roughly a palm's width below and to the right of the moon. You will need a telescope to see Mercury, shining as bright as some stars at magnitude -0.45.
The four bodies will be in the Leo constellation, making this a good opportunity to familiarize yourself with the stars of this popular night sky sight. The moon will be underneath the Lion's jaw, while Venus will be located between its front legs. Mars will be just beside one of its rear feet.
On Thursday (July 20), Mars will move even closer to the moon. Head outside around the same time on the following two nights and look to the west to watch the cosmic dance of these summer skywatching favorites.
If you are hoping to catch a closer look at the planets, the moon or anything else in the night sky, our guides to the best telescopes and best binoculars are a great place to start.
