1 Ceres's 4.6-year orbit around the Sun will carry it to its furthest point to the Sun – its aphelion – at a distance of 2.98 AU.

In practice, however, 1 Ceres's orbit is very close to circular; its distance from the Sun only varies by about 16.7% between perihelion and aphelion. This means that the difference in the amount of heat and light it receives from the Sun between aphelion and perihelion is extremely small.

Finding 1 Ceres

1 Ceres's distance from the Sun doesn't affect its appearance. From Cambridge, at the moment of aphelion it will not be observable – it will reach its highest point in the sky during daytime and will be no higher than 11° above the horizon at dusk.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

A chart of the path of 1 Ceres across the sky in 2016 can be found here, and a chart of its rising and setting times here.

The position of 1 Ceres at the moment it passes aphelion will be:

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
