PARADE OF PLANETS • September 2026

MORNING
Mars rises in the east around 1 AM in the constellation Gemini. This is not the best time to view Mars through a telescope because it is fairly far away from Earth and thus appears small—difficult to see any detail. Yes, it is reddish in color which makes it easier to identify. Mars gets close to Earth every 26 months and at these times it will appear large enough in telescopes to see its various features. The next time this will occur is February 2027.Jupiter rises around 3 AM in the constellation Cancer. Jupiter is always a favorite in a telescope, even a small one because the four Galilean moons are always visible as well as the two equatorial and parallel bands on its cloud “surface.” The Great Red Spot is not easy to recognize anymore because its color is pale and blends in with its surroundings. As a “star,” Jupiter is always brighter than any other star except for Venus.

EVENING
Venus is up in the western sky after sunset. You can’t miss it because it is the brightest “star” in the whole sky. It sets about 90 minutes after the Sun. 
Saturnin Pisces, rises in the east as the Sun is setting in the west. This is called Opposition (opposite the Sun). At opposition, Saturn is the brightest it gets in the sky, appears the largest in telescopes and stays in the sky all night long.

Remember • Twinkle Factor
The planets DO NOT normally twinkle like stars unless they are very close to the horizon or the atmosphere is extremely turbulent. So, even thought Saturn is not very bright, it is easier to identify because it does not twinkle. And, Mars is the same but every 26 months, it gets very bright and can't be missed. Mars also has a red tint to it.

WATCH

There should be a naked eye NOVA star showing for a few days in the night sky sometime during the next year. Click here for more information.

September 2026 Note​s

 About 90 minutes after Sunset

Constellations
The “Heart” of the Milky Way Band, that is, the direction to the center of our galaxy is just west of due south and somewhat above the horizon between Sagittarius and Scorpius. This is also the brightest part of the Band.

Summer Triangle.  If you look straight up at the top of the sky you will see the bright star Vega, in the little constellation Lyra. It is the brightest star forming the Summer Triangle. The third brightest star of the Summer Triangle is the nearby Deneb, the top star of the Northern Cross. The second brightest star that makes up the Summer Triangle is Altair in Aquila. It is higher up in the south but lower than Vega and Deneb. It ”pulls” the triangle into a nice isosceles! The Summer Triangle is rather large but once you recognize it, it be be easy to spot in the future—something you can share with others.

The very brightest star in the sky at this time of the year is Arcturus which is lower in the west. The curved Handle of the Big Dipper arcs to Arcturus (lots of arcs here). The Big Dipper is lower in the northwest.

Header Image
The celestial image used for this site's header is part of the Veil Nebula, a supernova remnant in the constellation Cygnus (the Swan) visible throughout most of the summer and fall. This triangular wedge is a fainter part somewhat between the two major sections that make up the Veil Nebula and it is called Pickering’sTriangle. I took this image using a 6-inch diameter refractor telescope.
