HD 183552, also known as HR 7411, is a probable spectroscopic binary[14] located in the southern constellation Telescopium. The system has a combined apparent magnitude of 5.74,[2] allowing it to be faintly visible to the naked eye. Based on parallax measurements from the Gaia spacecraft, it is estimated to be 337 light years distant.[1] The value is horribly constrained, but it appears to receding with a radial velocity of 14 km/s.[5]

This object is an Am star with a spectral classification of kA6hF2mF2 (II),[3] an evolved F-type star having the calcium K-line of an A6 star plus the hydrogen and metallic lines of an F2 star. Its current mass is 1.68 M☉[7] and is estimated to be 733 million years old,[1] having completed 83.1% of its main sequence lifetime. It has expanded to 4.7 times the radius of the Sun[8] and now radiates 45 times the luminosity of the Sun[9] from its photosphere at an effective temperature of 7,317 K.[11]
