Science
Physical
- Radius (estimated)
- 19 km · 1% of our Moon's radius
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~38 km) could be off by a factor of two.
Orbit around Neptune
- Distance from Neptune
- 0.157 AU
- From JPL orbital elements
- Orbital period
- 8.69 years
- From JPL orbital elements
- Eccentricity
- 0.5376
- From JPL orbital elements
- Inclination to the J2000 equator
- 47.83 °
- From JPL orbital elements
Radiation & temperature
- Insolation
- 0.00113 S⊕ · 1/883 of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history
- By
- M. Holman, J.J. Kavelaars, T. Grav, W. Fraser
S/2002 N 5 is the provisional designation of a small moon of Neptune detected in 2002 by M. Holman and colleagues. It has not yet been given a permanent name, and little is known about it beyond its discovery and orbit.
