Multiwavelength JWST Observations of (3200) Phaethon Show a Dehydrated Object with an Aqueously Altered Origin

We present JWST observations of the near-Earth asteroid (3200) Phaethon using NIRCam, NIRSpec, and MIRI to further investigate the composition of Phaethon’s surface. Our NIRSpec data confirms that Phaethon’s surface is dehydrated, showing no evidence of hydrated minerals in the 3 μ m region. We esti...
