Chi Cygni pulses once every 408 days. At its smallest diameter of 300 million miles, it becomes mottled with brilliant spots as massive plumes of hot plasma roil its surface. As it expands, Chi Cygni cools and dims, growing to a diameter of 480 million miles—large enough to engulf and cook our solar system out to the asteroid belt.
