10/01/2021 Ephemeris – Learn about exoplanets and have a star party tonight (virtually)

October 1, 2021 Comments off

This is Bob Moler with Ephemeris for Friday, October 1st. Today the Sun will be up for 11 hours and 41 minutes, setting at 7:22, and it will rise tomorrow at 7:42. The Moon, 3 days past last quarter, will rise at 2:49 tomorrow morning.

The Grand Traverse Astronomical Society hold a virtual meeting and program at 8 pm tonight via Zoom. For the program, yours truly will present Finding Exoplanets. Exoplanets are planets found orbiting other stars or rogue planets floating in interstellar space alone. We’ve actually only seen a handful of exoplanets, so most are detected by their effects on their host star. A virtual star party will start around 9 pm, hosted by Dr. Jerry Dobek, astronomy professor at Northwestern Michigan College, but only if it’s clear in Traverse City. It will feature Jupiter and Saturn, wonders of the northern part of the summer Milky Way. Instructions to join the meeting and a link can be found on the society’s website, http://www.gtastro.org.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT-4 hours). They may be different for your location.
