With an apparent magnitude of 9.1,[2] it is too faint to be detected with the naked eye but can be seen with a telescope. The star is relatively close at a distance of about 153 light years[1] but is receding with a heliocentric radial velocity of 34.4\u00a0km\/s.[6]HD 42936 is an early K-type star with the blended luminosity class of a main sequence star and a subgiant.[3] At present it has 87% the mass of the Sun and 91% the radius of the Sun.[7] The object shines at 51% the luminosity of the Sun[8] from its photosphere at an effective temperature of 5,138 K,[7] which gives it an orangish yellow glow. HD 42936 has iron abundance 151% that of the Sun, meaning it is metal enriched[10] despite an age of 10.9 billion years.[7]Planetary system[edit]In 2019, an  analysis carried out by a team of astronomers led by astronomer John R. Barnes of the Dispersed Matter Planet Project (DMPP) confirmed the existence of a super-Earth[7] in orbit around DMPP-3See also[edit]References[edit]^ a b c d e f Brown, A. G. A.;  et\u00a0al.
