Psyche’s day
~4.2 h
Synodic rotation of (16) Psyche

PhotoESO/LAMCC BY 4.0
Psyche’s present day is about 4.2 hours. Ferrais 2020 reads the shape as a slowed Jacobi ellipsoid that once spun nearer three hours. Four-point-two is a rounding of a spacecraft-grade period, not 42.
Four named
Hearth. Soul. Love. Longing.
Vesta is the hearth. Psyche is the soul. Eros is love. Himeros is longing. Four names from one old story, hung on four different rocks and one crater. The 42s are not the same kind. A spin pole is not a density. A cipher is not a catalogue number. The looking holds them without pretending they are one law.
- 42.23°Vesta
Hearth
The sacred fire. Spin pole. Moment 0.4208. Another world.

Soul
Metal world NASA is flying toward. Not the crater on Eros.
- 433433 Eros
Love
The love asteroid. Catalogue seat, not a 42. The 42s are rooms.
- 42Himeros
Longing
Attendant of Eros. English letters. A bowl on the love rock.
What it supports
A measured asteroid day. NASA: just over four hours. JPL 4.196 h is the same clock. The 4.2 h sits next to this Book’s 4°20′. Two instruments. Not one proof.
What it does not
Not 42. Not the 42″ coordinate. Not density as destiny.
