description KY Cygni Overview
KY Cygni is a heavily dust-enshrouded red supergiant star located in the Cygnus OB1 stellar association. It is classified as an M-type variable star and ranks among the largest known stars in the Milky Way. Astronomers estimate its radius to be around 1,400 times that of the Sun, though high levels of intervening dust make precise measurements difficult. If placed at the center of the Solar System, its photosphere would extend beyond the orbit of Jupiter.
help KY Cygni FAQ
How large is the star KY Cygni compared to the Sun?
KY Cygni ranks among the largest known stars in the Milky Way, with astronomers estimating its radius to be around 1,400 times that of our Sun. This massive size makes it a prominent subject of study for scientists observing stellar evolution.
Where is KY Cygni located in the night sky?
This red supergiant is located in the Cygnus OB1 stellar association within the constellation Cygnus. It sits thousands of light-years away from our solar system and is heavily obscured by cosmic dust.
What type of star is KY Cygni?
KY Cygni is classified as an M-type variable star, specifically a red supergiant. Its variable nature means that its brightness fluctuates over time as it expands and contracts.
Can you see KY Cygni with the naked eye?
Due to being heavily dust-enshrouded, KY Cygni experiences extreme dimming and cannot be seen without powerful telescopic equipment. The intervening dust absorbs much of its visible light before it ever reaches Earth.
