Tonight(Feb. 27 ), as darkness is falling, be sure to look toward the west-southwest sky to identify another gorgeous celestial tableau formed by a beautiful crescent moon and the dazzling world 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 steps roughly 10 degrees, so, Venus and the moon will appear a bit more than a half fist apart. These Venus-moon rendezvous take place on roughly a month-to-month schedule. If Venus were fixed and did not appear to move versus the star background, a Venus-moon encounter would take place 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 when using the background stars as a referral point. Due to the fact that Venus and the moon were together on Jan. 28, we might have anticipated a return engagement this previous Monday (Feb. 24 )if we tried to apply the”sidereal month guideline”to this schedule.Venus on the relocation Obviously, that rule didn’t work due to the fact that Venus is not fixed; it’s relocating its own orbit around the sun. From our Earthly perspective, Venus has actually appeared to move substantially to the east versus the star background. Back on Jan. 28, Venus was in the constellation Aquarius, the water provider. However today, it will appear

to have moved more than 35 degrees to the east, where it currently lives in the constellation Pisces, the fishes. The moon had to travel that much more throughout the sky to catch up to Venus. Since the moon appears to cross the sky at approximately 13 degrees per day, it needs three more days to reach 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 items in the night sky.

And so is our Earth

Incidentally, another factor that needs to be thought about is Earth’s motion around the sun. If, in fact, you searched for the crescent moon this past Sunday night (Feb. 23), you would not have been able to see it because it was at brand-new stage and for this reason too close to the sun to be seen. That’s because, throughout the 26 days that had actually expired considering that Jan. 28, Earth’s movement around the sun would have triggered the sun’s position in the sky to shift to the east also– in this case, right into the extremely exact same area that Venus and the moon inhabited on Jan. 27.

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

And lastly, if clouds unknown your view of Venus and the moon tonight, do not stress– future opportunities to see them together once again will come on March 28 and April 26.
