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 Seattle, at the moment of aphelion it will not be readily observable since it will lie so far south that it will never rise more than 19° above the horizon.
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.
