VY Canis Majoris

Do you ever wonder what is the biggest thing in the universe? Well today you will find out. Some say it is the sun, well they are absolutely incorrect. It is actually a star called VY Canis Majoris. The sun is also known as the yellow dwarf compared to VY Canis Majoris. It then goes Mu Cephei, then Antares A, next Pistol Star, then Rigel, next Aldebaran, then Arcturus, then Pollux, then Sirius, then the sun, then uranus, next Neptune, then Earth, then venus, then Mars, then mercury, Lastly Earth’s moon and that is the order of the star’s and planet’s. Here is a little movie about what I was talking about.

VY Canis Majoris:
It is about 2000 times the size of our Sun with a diameter of 3,063,500,000,000m.The surface temperature of the star is comparatively cooler than our Sun with 3,000K compared to our Sun's 5,800K. If this star replaced our Sun in the Solar system, it would extend up to Saturn. It is about 4,900 light years away from Earth. The surface temperature of the star is comparatively cooler than our Sun. The VY Canis Majoris is so large, that if an airplane traveling 900 km/h were to circle it, it would take over 1100 years to make one journey!


  1. Hey Jordan,
    Its great to see you have been learning at school and at home. I always thought that the sun was the biggest thing in the universe but now that I have read this I now know VY Canis Majoris is. This piece of writing was fun to read. Anyway, I can't wait to read more interesting post. KEEP UP THE GREAT WORK JORDAN!!!


  2. Well I certainly learnt something new! Very cool work Jordan. Maybe you could do some more research into the temperature. You are good at maths - I'm sure you could work out how hot VY Canis Majoris is in celsius scale.
    I love reading your extra learning Jordan.
