How to see Venus shining with the moon tonight

Venus and the moon will make a close approach in the evening sky on Feb. 27, 2020. The pair will be in conjunction, meaning they will be at the same celestial longitude, at 6:51 a.m. EST (1151 GMT). For skywatchers in the U.S., Venus and the moon will be below the horizon at the time of conjunction, but they will become visible in the evening as dusk fades. (Image credit: SkySafari App)

Tonight (Feb. 27), as darkness is falling, be sure to look toward the west-southwest sky to spot another beautiful celestial tableau formed by a lovely crescent moon and the brilliant planet Venus

Venus will appear to hover far to the right of the moon. The objects will be separated by about 6.5 degrees. The width of your clenched fist held at arm's length measures roughly 10 degrees, so, Venus and the moon will appear a bit more than a half fist apart. 

These Venus-moon rendezvous occur on roughly a monthly schedule. If Venus were stationary and did not appear to move against the star background, a Venus-moon encounter would occur every 27 days, 7 hours and 43 minutes. This is called a "sidereal month," which is the length of time it takes the moon to circle Earth once using the background stars as a reference point. Because Venus and the moon were together on Jan. 28, we might have expected a return engagement this past Monday (Feb. 24) if we tried to apply the "sidereal month rule" to this schedule.

Venus on the move

Of course, that rule didn't work because Venus is not stationary; it's moving in its own orbit around the sun. From our Earthly viewpoint, Venus has appeared to shift considerably to the east against the star background. Back on Jan. 28, Venus was in the constellation Aquarius, the water carrier. But today, it will appear to have shifted more than 35 degrees to the east, where it currently resides in the constellation Pisces, the fishes

So, the moon had to travel that much more across the sky to catch up to Venus. Because the moon appears to move across the sky at roughly 13 degrees per day, it needs three more days to catch up to Venus. That takes us to tonight, when once again we will be treated to an eye-catching sight in our western twilight sky between the two brightest objects in the night sky. 

And so is our Earth

Incidentally, another factor that must be considered is Earth's movement around the sun. If, in fact, you looked for the crescent moon this past Sunday night (Feb. 23), you wouldn't have been able to see it because it was at new phase and hence too near to the sun to be seen. That's because, during the 26 days that had elapsed since Jan. 28, Earth's movement around the sun would have caused the sun's position in the sky to shift to the east as well — in this case, right into the very same region that Venus and the moon occupied on Jan. 27. 

By tonight, however, the moon will be well clear of the sun and readily visible in the west-southwest sky with Venus. Now gleaming at magnitude -4.3, Venus has been ascending dramatically higher in February and now is setting more than 3.5 hours after the sun. No other star (other than the sun) or planet can come close to matching Venus in brilliance. During World War II, aircraft spotters sometimes mistook Venus for an enemy airplane. There were even cases where Venus drew anti-aircraft fire. 

In the western evening sky on Feb. 27, 2020, the young, crescent moon will be a lovely sight, sitting a generous palm's width to the left (or 6 degrees to the celestial south) of very bright Venus. When viewed in a telescope, Venus will exhibit a gibbous phase (inset). (Image credit: Starry Night (opens in new tab))

And lastly, if clouds obscure your view of Venus and the moon tonight, don't fret — future opportunities to see them together again will come on March 28 and April 26.

    I was out observing this celestial event from about 1730-1830 EST. Clear skies, winds from NW and temperature 2C. Quite a lovely view using my 10x50 binoculars and 90-mm refractor telescope. Sunset near 1757 EST and earthshine very obvious on the waxing crescent Moon, especially after 1812 EST and later.

    From my southern hemisphere perch crescent was pointing to the left in the Northwest and about 5 degrees above Venus. Life in this upside down reality sure looks different here. ;)
