Deep sky objects

It has no Messier objects but it has some deep sky objects like:

  • NGC 1705- This is a dwarf galaxy which is irregular and is some 17 million light-years away. This has a magnitude of 12.8 and is deep blue in color. It is a 13 million old galaxy that contains a number of stars young and old and is also a great way of studying the evolution of galaxies.
  • SPT-CL J0546-5345- This a huge galaxy cluster that is 7 billion light-years away and is approximately 13.7 billion years old. It is one of the biggest galaxy clusters that can be found and has almost 800 trillion stars.
  • Pictor A- This a radio galaxy that is 485 million light years away and has a massive black hole that sends out a jet of rays.

It has a visual magnitude of 3.27 and is some 660 million years old. It is also 13 times more luminous. It is a fast spinner as it can rotate at a velocity of 206 km. On the mercury, it is known as the South Pole star.

This star is located to the west of the star Canopus and the constellation Carina. This star has a mass that is 8 times more than Jupiter.
  • Gamma Pictoris- The third brightest star of the constellation; it is an orange giant star that has an apparent magnitude of 4.50 and is 174 light years distant. This star is some 11 times bigger than the sun.
  • Delta Pictoris- This star has an apparent magnitude of 4.72 and is some 1655 light years away from the sun. This star is known to be a beta Lyrae variable that is quite variable.
  • Kapteyn’s star- The kapteyn’s star is some 12.76 light years distant from the earth and is it can be easily seen from a small telescope. This star is cooler than the sun and this star belongs to the stellar class.
  • AB Pictoris- This is the main orange sequence star that has a magnitude of 9.16 and is some 150 years distant from the sun. The AB Pictoris in mass is 13.5 times more than Jupiter.

Apart from these stars, there is the HD 40307 which have six planets in its orbit and the HD 41004, this is a multiple star system.
