Editing Cetus (section)

===Ecliptic===
Cetus is not among the 12 true [[zodiac]] constellations in the [[Epoch (astronomy)|J2000 epoch]], nor classical 12-part zodiac. The [[ecliptic]] passes less than 0.25° from one of its corners. Thus the Moon and planets will enter Cetus (occulting any stars as a foreground object) in 50% of their successive orbits briefly, and the southern part of the Sun appears in Cetus for about 14 hours each year on March 27 to 28. Many asteroids in belts have longer phases occulting the north-western part of Cetus, those with a slightly greater [[inclination]] to the ecliptic than the Moon and planets.

[[Astronomy on Mars#Celestial poles and ecliptic|As seen from Mars]], the ecliptic (apparent plane of the Sun and also the average plane of the planets which is almost the same) passes into it.
