01/21/2019 – Ephemeris – Venus and Jupiter will pass each other tomorrow morning

January 21, 2019 Comments off

Ephemeris for Martin Luther King Jr. Day, Monday, January 21st. Today the Sun will be up for 9 hours and 23 minutes, setting at 5:35, and it will rise tomorrow at 8:11. The Moon, at full today, will rise at 6:23 this evening.

I hope you’ve been noticing the bright planets Venus and Jupiter in the morning this month on the few mornings that have been clear. Jupiter and Venus have been drawing together. And tomorrow morning they will pass each other. The event is called a conjunction. To astronomers it’s a cool looking event, where the planets happen to be along the same line of sight. They are nowhere near each other in actuality. Venus is 76 million miles (120 million km) away, while Jupiter is 555 million miles (894 million km) away. It doesn’t affect anything on the Earth. It’s just cool looking. After this, Jupiter will move farther and farther from the Sun, while Venus will appear to fall back towards the Sun, even though they both are traveling eastward against the stars.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
