Our local guide to observing celestial objects and events

July 2018

It’s show time for the visible planets this month. Venus still glows brilliantly low in the west all month around 9 or 9:30 pm. Mercury can best be found on July 14th, at 9 pm. when it is just below a thin crescent Moon. Use binoculars. Or you can look between July 1 and 14 as Mercury hovers about 16 degrees below right of Venus.

Jupiter gleams in the south around 10 p.m. on the 1st but has moved to the southwest by the 31st.

Yellowish Saturn glows in the southeast moving to the south at the same times mentioned for Jupiter. Moon pairings listed in the highlights will help you identify those two planets.

Now is an excellent time to observe Saturn and its rings through a telescope.

But Mars tops the charts as it nears its closest approach to Earth since 2003. On July 31 Mars will be 0.385 AUs from Earth (1 AU or Astronomical Unit is the average Earth-Sun distance or about 93 million miles) so Mars will be just 36 million miles from Earth.

Now go enjoy nature’s free sky show and be sure to stop by the new Bell Museum from July 14th on and ask our planetarium folks to show you where to look.

When viewing planets, stars or constellations in the night sky, it is helpful to use a sky map.

Minnesota Starwatch is another great resource for tracking the night sky.
