On 9 July, our very own John Coxgave a fascinating talk about our
147 nearest neighbours.All these
stars are within 20 parsecs of us
His Image of Keid caught my
attention as it was taken, by
John with a simple Philips
Toucam webcam on the
Societies 14" Meade SCT.
This triple star is the only known system that displays three
different types of star. The Primary is yellow G9V class.
The other two components are dwarf stars.
A red dwarf type DM and a white dwarf of type DA.
Also it is the only system where the dwarf stars can easily be seen.
The Star Keid is also known as Omicron 2 Eridanus
Distance is 16 light years with Mags: 4.4, 9.5, 11.1
RA : 04h 15m 45.28s Dec : -7° 37' 06.4"
It is well placed for us to observe in winter as it is to the right
of Rigel in Orion (RA : 05h 15m 01.14s Dec : -8° 11' 11.4")
