OCCULTATION

Skygazers watched a rare celestial event when the moon came between Earth and Mars. The phenomenon is known as occultation.

Important points:

  • An occultation is an event that occurs when one object is hidden by another object that passes between it and the observer. The term is often used in astronomy.
  • If the closer body does not entirely conceal the farther one, the event is called a transit. Both transit and occultation may be referred to generally as occlusion; and if a shadow is cast onto the observer, it is called an eclipse.
  • Occultations by the Moon: The term occultation is most frequently used to describe those relatively frequent occasions when the Moon passes in front of a star during the course of its orbital motion around the Earth.
