Struve 2398 A is an orange star, in the constellation Draco. The light you see from it tonight left it around 2014.
Where to find it
From mid-northern latitudes, such as New York, Rome or Tokyo, it never sets: it circles the pole all night, all year.
Too faint for the naked eye: you’ll need binoculars. Apparent magnitude 8.94.
What it’s like
It gives off about 0.30% of the Sun’s light.
Its surface is at about 3,800 degrees.
It is 11.6 light years away: 110 trillion kilometres.
It is the star of people born around 2014: the light that left it then is reaching Earth now.
