PRESENTATION OUTLINE
Bigger orbit-
because the sun is bigger, for planets to be at a reasonable distance to not burn up, the planets would have to have a much bigger orbit.
Length-
If a star was twice our sun, with such a huge mass, and only twice as much fuel and gases to sustain it, this star wouldn't last as long as our sun.
Gravitational pull-
If the sun was so much bigger, the gravitational pull would be much greater.
Orbit-
The orbiting of planets would be much faster as the gravitational pull of the sun would be much stronger, and years would be much faster.
Climate-
Earth would become much hotter due to the larger amounts of heat coming off the sun. Glaciers and ice caps would melt, and oceans would evaporate.
Humans-
It would be too hot to live on earth, and humans would be incinerated in seconds by the sheer heat rays. And no water would be left on earth.
Black holes-
If the sun twice as large, collapsed on itself, gravity would take over, and other forces would let up, causing a black hole.
