The planets in detail

mu Leo b is a Neptune-like world with about 13.30 Earth radii and 762.80 Earth masses. It orbits mu Leo at 1.1000 AU with a 358-day year, and no published equilibrium temperature. It was confirmed in 2014 via radial velocity (Doppler) measurements.

Discovery

The single planet in the mu Leo system was confirmed in 2014 using radial velocity (Doppler) measurements. Detection facilities: Bohyunsan Optical Astronomical Observatory.

Observing from Earth

Exoplanets cannot be resolved visually with amateur telescopes — the host star's glare is overwhelming and even space-based direct imaging requires sophisticated coronagraphs. What you can observe is the host star itself at right ascension 148.1899°, declination 26.0067°. Use the 3D orrery above to inspect orbital geometry, planetary scale, and the habitable-zone overlay — the orbits are computed from the published Keplerian elements and animate at user-controlled time rates.
