NGC 1101 is a lenticular galaxy in the Cetus constellation,[1][2] and is an estimated 331 million light-years away from Earth. It was discovered on 22 November 1876 by French astronomer Edouard Stephan, who described it as "very faint, small, round with a brighter middle".[3]
NGC 1101 contains a flat-spectrum radio source[4] and it has a HI line width.[5]
To date, a non-redshift measurement gives the galaxy a distance of 81,700 megaparsecs (Mpc) or equal to ~266 million light-years.[6] This value is just outside the Hubble distance values. According to NASA/IPAC database, the diameter of NGC 1101 is calculated to be around 41.3 kiloparsecs (~135,000 light-years) if the Hubble distance were to calculate it.
