Jupiter and Neptune will join the moon in the sky.

At 5:58 a.m., the moon will be visible. On Saturday, it starts at 0958GMT. The moon is visible for most of the night at this time of the month. When the moon is in the sky, it becomes a full moon.

The Harvest Moon is a full moon in September that coincides with the autumnal equinox, which is the beginning of the harvest season. Jupiter and Neptune will be close to the full moon this month.

September's full moon can be seen when the Harvest Moon occurs.

Earth is between the giant planet and the sun and Jupiter will be bright this month. Jupiter is bright enough to be visible with the naked eye, but can be seen through binoculars or a telescope. At midnight, Jupiter will appear to the left of the moon, then shift to the right at 5:47 a.m. The NASA Science's Daily Skywatching Guide is open in a new tab A fist at arm's length is around 10 degrees.

Jupiter will be visible in the sky, but Neptune will not be as visible. Just after 10:00 p.m., the moon will rise. The sky will be travelling west towards the southeastern stars of the Aries constellation. Neptune will be just to the west of the moon, but you can find it by looking for the star 20 Piscium, which is a few fingers above the moon.

Neptune will be somewhat faint with a magnitude of 7.8, and the bright full moon will make it even more difficult to view; Neptune will be brighter on the following nights and will be at its best when it reaches opposition on September 16.
