HD 183552
HD 183552, also known as HR 7411, is a probable spectroscopic binary located in the southern constellation Telescopium. The system has a combined apparent magnitude of 5.74, 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. The value is horribly constrained, but it appears to receding with a radial velocity of . This object is an Am star with a spectral classification of kA6hF2mF2 (II), 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  and is estimated to be 733 million years old, having completed 83.1% of its main sequence lifetime. It has expanded to 4.7 times the radius of the Sun and now radiates 45 times the luminosity of the Sun from its photosphere at an effective temperature of . References
