It lies in the northern part of the constellation at a distance of about 790 ly, east of Aludra in Canis Major and just north of the white supergiant, 3 Puppis. This object is visible to the naked eye as a faint, red-hued star with an apparent visual magnitude of 4.59. It is moving further from the Earth with a heliocentric radial velocity of +32.4 km/s. thumb|left|A light curve for 1 Puppis, plotted from Hipparcos data The Hipparcos data for 1 Puppis shows low amplitude (0.007 magnitude) variability with a period of 1.8094 days.Koen Chris Eyer Laurent New periodic variables from the Hipparcos epoch photometry Monthly Notices of the Royal Astronomical Society March 2002 331 1 45–59 10.1046/j.1365-8711.2002.05150.x astro-ph/0112194 2002MNRAS.331...45K free The International Variable Star Index classifies the 1 Puppis as a star with starspots that cause the brightness to change as it rotates, and which varies in visual magnitude from 4.58 to 4.63.NSV 3708 https://www.aavso.org/vsx/index.php?view=detail.top&oid=42332 The International Variable Star Index AAVSO 3 October 2022 This is a red giant star with a stellar classification of M1 III, having exhausted the hydrogen at its core and evolved away from the main sequence. The star is radiating 1,509 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,111 K. It has several visual companions: component B, of magnitude 13.7 and angular separation of 26 arcsecond, C, of magnitude 9.21 and separation 78.8, and D, of magnitude 10.84 and separation from C of 1.3.2001AJ....122.3466M 10.1086/323920 The 2001 US Naval Observatory Double Star CD-ROM.
