Is Canis Majoris a hot star or a cold star?
A very large and luminous star, VY CMa is among the most extreme stars in the Milky Way and has an effective temperature below 4,000 K (3,730 °C; 6,740 °F).
Can you see Canis Major in summer?
Canis Major is not possible to see throughout summer, as it passes in the daytime sky. As the constellation declination is at southern latitudes, it remains below the equator for most northern hemisphere latitudes at the beginning of winter.

Why is the Dog Star not visible in July?
But in North America, we refer to the first visibility of the Dog Star as the end of the “dog days,” instead. During those sultry days of July into early August, Sirius is invisible due to its proximity to the sun in the sky.
Is Canis Major visible all year?
The constellation Canis Major, the great dog, is located in the southern hemisphere of the sky. It is visible in the northern hemisphere from December through March. It can be seen at latitudes between 60 degrees and -90 degrees.
Is there a Sirius C star?
More recent (and accurate) astrometric observations by the Hubble Space Telescope ruled out the existence of such a Sirius C entirely. The 1995 study predicted an astrometric movement of roughly 90 mas (0.09 arcsecond), but Hubble was unable to detect any location anomaly to an accuracy of 5 mas (0.005 arcsec).
Is Sirius hotter than Sun?
Sirius is classified by astronomers as an “A” type star. That means it’s a much hotter star than our sun; its surface temperature is about 17,000 degrees Fahrenheit (9,400 Celsius) in contrast to our sun’s 10,000 degrees F (5,500 C).
