VX Sagittarii
VX Sagittarii, one of Red supergiant star.
VX Sagittarii, also known as HIP 88838, is a red hypergiant star with a diameter pulsating between 1.120[1] and 1.940 times Sun,[2] a temperature between 3.200 and 3.400 degrees Kelvin.[3] The star has a pulsation period of 732 days and is located 1.5 kiloparsecs away from the Earth. Older studies show significantly higher temperatures.[4][5]
