Due to the brightness, twinkling and color changes  people sometimes report Sirius as a UFO! In fact, these changes happens when such a bright star as Sirius shines through the blanket of Earth’s atmosphere. The varying density and temperature of Earth’s air affect starlight, especially when we’re seeing the star low in the sky. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years.  Sirius system is one of Earth's  n earest neighbours. Sirius A is about twice as massive as the Sun  .It is 25 times more lu

Then all of them awarded place in the sky.Ophicus with serpent above Scorpion,Orion to the apposite side of Scorpion,so that they never encounter each other.T
