EYES TO THE SKY: Celestial numbers in the spirit of Valentine’s Day

It’s 11 o’clock on a clear, moonless night when, although ready to call it a night, I pause at a glass door that looks out to the southwestern sky: I am moved by an urge for contact with the stars.

Planet Venus, the third brightest celestial body in Earth’s skies—after the sun and moon—is the closest planet to Earth in our solar system. Named for the Goddess of Love, planet Venus is known as the Evening Star.

There are six planets in the sky after sunset in mid-to-late February. They all lie along the sun’s path, the green line on our chart. You’ll want a clear view to the west because—as seen from across Earth—four of them set soon after the sun. And two require optical aid to be seen (the two marked with crosses on our chart). Watch for Saturn dropping toward the horizon, while Venus and Mercury climb up from sunset. Neptune is next to Saturn, but you will need a telescope to see it. Uranus is higher in the sky; you might see it with binoculars. The easiest planet—the one everyone will be able to see with no problem—is bright Jupiter. Watch for this mighty world arcing across the sky as the night passes. And watch for the moon near Jupiter the evening of Feb. 26! Courtesy of EarthSky.org.

The smaller the number, the brighter the celestial body.

The apparent magnitude of the Sun is -26.74; Full Moon: -12.6 to -12.7 magnitude.

Venus, -3.91m, sets at 6:09 p.m.; Mercury, -0.88m, sets at 6:51 p.m., Saturn, 1.09m, sets at 8:13 p.m.

Today: Day length 10 hours, 32 minutes, Darkness/astronomical twilight 5:17 a.m., Dawn 6:23 a.m., Sunrise 6:52 a.m., Sunset 5:24 p.m., Dusk 5:52 p.m., Nightfall 6:58 p.m.

It’s 11 o’clock on a clear, moonless night when, although ready to call it a night, I pause at a glass door that looks out to the southwestern sky: I am moved by an urge for contact with the stars. The sight of Orion the Hunter and The Greater Dog, Canis Major, fills my viewshed from southwest to west. How enormous they are! A smile of recognition moves my face, my spirit.
