Title: Pistol Star


1
Pistol Star
  • By Aaron Levett

2
SIZE!!!
  • The Pistol Star is about 450,520,000 kilometers
    in diameter, smaller then Betelgeuse, but
    compared to the Sun, it is huge. The Sun is about
    1,392,000 kilometers in diameter. The pistol star
    is very big compared to Sirius A, Pollux, Rigel,
    and Deneb. The Pistol Star is almost 400 times
    bigger than the Sun.

3
Distance From Sun
  • The Pistol star is about 25,000 light years away
    from our sun. Wow!!!

4
Temperature
  • The Pistol Star is very close to the newest
    brightest star, with a range of 18,000-32,000
    degrees Kelvin, or 17727-31727 degrees Celsius.
    (See next page) The sun is only 6000 degrees
    Celsius.

5
How to calculate Kelvin
  • From a degrees Celsius, you take the amount of
    degrees, and then add by 273.15 degrees. This is
    how you find Kelvin,
  • Example 1000 degrees Celsius is 1273.15 degrees
    kelvin.
  • Example Water Freezes at 273 degrees Kelvin, and
    boils at 373 degrees Kelvin.

6
Color
  • The Pistol Star is A blue hyper giant, compared
    to our sun which is yellow.

Sun Is actually much smaller than comparison
shown.
7
Brightness
  • The Pistol star is one of the stars with the
    greatest absolute brightness. It gives of as much
    as 2 million times the amount of light in our
    sun. In 20 seconds, it gives off as much light
    and energy as our sun does in one year.

8
Hertsprung-Russell Diagram
  • As you can see, the pistol star is a little
    brighter then to fit on diagram, so I added an un
    proportional line, adding the number of solar
    units. The dot is showing the temperature and
    color of the star.

9
Constellation
  • The Pistol star is located in the constellation
    Sagittarius.
  • Sagittarius , in Greek mythology is known as a
    centaur, which is half human, half horse. He was
    known as The Archer.
  • The Sagittariuss name was Chiron, and was
    accidentally shot by Hercules. In Recognition,
    Zeus put him in the sky, as the constellation
    Sagittarius.

10
Life cycle
  • The pistol star, is a blue hyper giant, there
    fore it started from a nebula. It then evolved
    into a high-mass protostar. It is currently
    unknown what stage of its life the star is in,
    but scientists predict that in 1-3 million years
    it will explode into a supernova, or maybe even a
    hyper nova, which is even greater. It is
    currently predicted to be in its middle of life,
    because it burns off fuel so fast.
