Iota Serpentis

Iota Serpentis (ι Ser, ι Serpentis) is a star system in the constellation Serpens, in its head (Serpens Caput). It is approximately 192 light years from Earth.

At the centre of the system is a spectroscopic binary, Iota Serpentis A and B. These are both white A-type main sequence dwarfs and both have apparent magnitudes of +5.3. This binary appears to have an orbital period of 11 years; spectroscopic evidence indicates a third companion of A and B. A and B also have two distant companions, Iota Serpentis C, a 13th magnitude star 143 arcseconds away and Iota Serpentis D, a 12th magnitude star 151 arcseconds distant.

Famous quotes containing the word iota:

    “The terrible thing is that one cannot be a Communist and not let oneself in for the shameful act of recantation. One cannot be a Communist and preserve an iota of one’s personal integrity.”
