Navagraha Homam is a Vedic fire ritual in which offerings are made to the nine grahas, Surya, Chandra, Mangal, Budh, Guru, Shukra, Shani, Rahu and Ketu. Each graha is invoked with its own mantra and, in many traditions, with its specific samidha (holy wood) and grains.
Families often choose it when an astrologer suggests graha shanti, at the start of a new phase of life, or as a general ritual for balance and harmony. It is also commonly performed as part of larger ceremonies such as griha pravesh or weddings.
It can be performed at home, at a venue or through an online sankalp with the family joining by video.
