Science
Physical
- Radius (estimated)
- 1 km
- Sized from its brightness assuming a dark (~0.04) surface — never resolved, so the true diameter (~2 km) could be off by a factor of two.
Orbit around Jupiter
- Distance from Jupiter
- 0.161 AU
- From JPL orbital elements
- Orbital period
- 2.09 years
- From JPL orbital elements
- Eccentricity
- 0.3261
- From JPL orbital elements
- Inclination to the J2000 equator
- 157.28 °
- From JPL orbital elements
Radiation & temperature
- Insolation
- 0.0346 S⊕ · 3% of the sunlight Earth receives
- Computed from the distance to the Sun (inverse-square; Earth's sunlight = 1), before any atmosphere.
Discovery & history
- By
- S.S. Sheppard
S/2018 J 5 is the provisional designation of a small moon of Jupiter detected in 2018 by S.S. Sheppard. It has not yet been given a permanent name, and little is known about it beyond its discovery and orbit.
