Monday morning’s sky will be quite crowded by planet-watching standards.
In the predawn hours, our nearest neighbors – Mars, Venus and a crescent Moon – will appear along with more distant but massive Saturn on the horizon.
To catch it, look for the moon where you are in the east-southeastern sky. The planetary trio will appear slightly above it, forming a triangle with Mars to the right and the other two planets to the left of the moon just a bit.
The entire arrangement should be visible to the naked eye if you’re in a location with minimal weather and light pollution.
To get a closer look, a pair of binoculars might help, and of course a telescope can allow you to resolve the individual worlds in slightly more detail. The cloudiness of Venus, redness of Mars and majestic rings of Saturn are easier to make out with more powerful magnification.
For orientation, Venus should be the brightest and highest in the sky of the planets.
If you have a slightly more skilled eye for skywatching, Jupiter will also be in the sky in the morning, although harder to spot. InTheSky is a good source for the exact details of where and when to look from your specific location.
While these planets transit in and out of view all the time, Venus, Saturn and Mars actually won’t appear this close together in the sky again until 2040, so it’s worth waking up early to be able to see more than half our solar system’s planets at once.
