Moon and star Antares Tonight

Moon and star Antares near each other on May 15

Tonight | EarthSky

The planet Saturn shines over the southeast horizon at nightfall on May 15, and then the moon and the star Antares follow Saturn into the sky by around 10 p.m. local time (at mid-northern latitudes). At more southerly latitudes, the moon and Antares rise at an earlier hour. Look for the waning gibbous moon and Antares before going to bed on this night.

Antares, the brightest star in the constellation Scorpius, represents the Scorpion’s beating Heart. Beating? Yes, because from our northerly latitudes we tend to look at Antares low in the south, and the atmosphere causes it to scintillate. Thus Antares, a red star, is know to twinkle fiercely.

Antares is a red supergiant star, whose volume is a few hundred million times greater than that of our sun. If Antares replaced the sun in our solar system, its circumference would extend all the way into the asteroid belt in between the orbits of Mars and Jupiter.
