Planetary Combustion (Asta) — New Endpoint, Verified Against BPHS

A planet too close to the Sun is classically considered "combust" — weakened by proximity to solar light. It's a real, load-bearing concept in Parashari analysis, and until now this API had no dedicated endpoint for it.

The classical orb thresholds

Combustion orbs vary by planet, and — for Mercury and Venus — by whether the planet is retrograde. These figures were cross-verified across two independent sources before shipping, not taken from a single reference:

Why Rahu and Ketu are excluded

Rahu and Ketu are shadow points — the Moon's orbital nodes, not physical bodies. Classically they never combust; a separate concept (Grahan Yoga) applies when a node conjoins the Sun, with its own disputed orb thresholds across sources. This endpoint deliberately doesn't conflate the two — it only reports combustion for the six physical planets it classically applies to.

What the response tells you

combust_planets is the quick list; detailsgives every planet's exact angular separation from the Sun, which orb was applied (including the retrograde-tightened value where relevant), and whether it crossed the threshold. Available on Starter plan and above.
