Get to know Canopus, the Second Bright Star in the Night Sky

Canopus is rarely studied because it is not seen in the Northern Hemisphere.

REPUBLIKA.CO.ID, JAKARTA — One of the bintang the brightest is Canopus. Bright Star Canopus best seen in the southern hemisphere, and is located in the constellation Carina.

Quoted from Space, Canopus is a class F giant in the main sequence of stars. Canopus’ mass is comparable to that of the sun. Canopus’ distance from Earth is estimated to be 313 light-years based on parallax measurements made by the Hipparcos spacecraft.

Canopus is a less studied star because it is not visible from most of the Northern Hemisphere. In addition, because there are so few other stars of its kind (hydrogen-fused class F giants), it is difficult to judge the star’s inherent brightness.

As a result, several incorrect calculations of Canopus’ luminosity were made, with some estimates reaching 60,000 times the sunlight. After the launch of the Hipparcos satellite by the European Space Agency (ESA) in the 1990s, more precise measurements were finally made.

According to the American Space Agency (NASA), the mission was “the first space mission dedicated to measuring the position, distance, motion, brightness, and color of a star. Hipparcos measurements determined Canopus’ location (313 light years away) and brightness (at least 12,000 times that of the sun). ).

Even though it is far from Earth, its luminosity makes it the second brightest star in the night sky. The brightest star in the night sky is Sirius which is 8.3 light years away.
