Epsilon Telescopium
What is Epsilon Telescopium
Epsilon Telescopii is a yellow G-type giant about 418 light-years away, in a modern constellation drawn by Lacaille to honour the instrument that transformed astronomy. Its spectral type echoes that of the Sun, but the resemblance ends there: it has already exhausted the hydrogen in its core and swollen into a slow-burning lighthouse —a glimpse of our own star's distant fate.
