Tomorrow morning – November 3, 2015 – greet the last quarter moon. Plus, see the conjunction of the brightest planet Venus and fainter, redder Mars. Those two are only a short hop beneath the largest planet Jupiter. It’ll be the closest Venus-Mars conjunction on the sky’s dome until October 5, 2017!

Venus-Mars conjunction, with Jupiter nearby.
Last quarter moon of November 3.
Venus-Mars conjunction, with Jupiter nearby. All three worlds made a planetary trio from about October 24 to October 29. That means that all three fit within a 5-degree circle on our sky’s dome, and were visible in a single binocular field. A Venus-Jupiter conjunction came October 26.
Now Jupiter has swept up above Venus and Mars in the east before dawn. And Mars has edged up slowly in the east before dawn, as Venus has begun its slow creep back into the sunrise. And so it was inevitable that Mars and Venus would meet on our sky’s dome.
The Venus-Mars conjunction comes at about 16 UTC on November 3. In other words, that when Venus and Mars have the same right ascension (similar to celestial longitude) on the dome of Earth’s sky.
We’ve had many questions about where these worlds lie, in the space of our solar system. Venus passed between the Earth and sun on August 15 and is now fleeing ahead of Earth in its smaller, faster orbit. Jupiter and Mars, meanwhile, are both on the far side of the solar system from us. The chart below – from Heavens Above – shows the view on November 3.
EarthSky lunar calendars are cool! They make great gifts. Order now. Going fast!
Last quarter moon of November 3. The precise moment of the last quarter moon is November 3 at 12:24 UTC. Although the last quarter moon happens at the same instant worldwide, the time by the clock varies by time zone. At U.S. time zones, the November 3rd last quarter moon takes place at 7:24 a.m. EST, 6:24 a.m. CST, 5:24 a.m. MST and 4:24 a.m. PST.
At last quarter, the moon’s disk is half-illuminated in sunlight and half-engulfed in the moon’s own shadow. The lunar terminator – shadow line – shows you where it’s sunset on the waning moon. The quarter moon’s illuminated limb outlines the moon’s noontime meridian whereas the dark limb outlines the moon’s midnight meridian.
If you could see the back side of the waning moon, the lunar terminator would you where it’s sunrise. As always, the terminator on the near side of the waning moon shows you where it’s sunset; and the terminator on the near side of the waxing moon shows you where it’s sunrise.
Bottom line: The conjunction of Venus and Mars takes place on the morning of November 3, 2015. It’s their closest conjunction until October 5, 2017. There’s also a last quarter moon in the sky that morning. Keep your eyes glued to the predawn sky in early November as the waning crescent moon sweeps by the star Regulus and then the three morning planets: Venus, Mars and Jupiter.
