PLANETARY ASTRONOMY & GRAHA TAXONOMY☽︎ Chandra (Moon) in Sidereal Jyotish
In the nine-planet system of Sanskrit positional astronomy, Chandra (Candra (Soma), Moon) is a benefic (saumya) sattvic luminary governing perceptual mind (Manas), maternal lineage, lunar phase luminosity (Paksha Bala), bodily fluids, and Janma Rashi. Within the vectorized reference corpus (jyotish_corpus_core_v3), Chandra appears in 5,848 verified passages and 3,188 numbered shlokas across 18 Sanskrit treatises.
Chandra (Moon) rules Karka (Cancer, 90° to 120°), reaches deep exaltation at Vrishabha 03°00' (Taurus), and enters deep debilitation at Vrishchika 03°00' (Scorpio). In the 120-year Vimshottari Dasha cycle, Chandra governs a major planetary period of 10 Years across the lunar mansions Rohini, Hasta, Shravana.

High-precision integration for Chandra under DE441
According to Brihat Parashara Hora Shastra Chapter 3 Verses 24 to 25 and Brihat Jataka Chapter 2 Verses 2 to 9, Chandra gains full directional strength in the Fourth House (Sukha Bhava) and requires at least 6.00 Rupas (360 Virupas) in six-fold Shadbala. For solar proximity and heliacal visibility of Chandra, classical mathematical astronomy applies a strict standard: Chandra enters solar conjunction (Amavasya) within 12°00' of Surya.
