Solar space
</h1>
<h2>
Solar space is the space beyond planet earth and between celestial bodyies. Solar space is not all empty-it is a hard vacuum full of low density particles such as plasma,hydrogen,and helium.The baseline teperature of solar space is 2.7 kelvins (-270.45 C -454.81 F.) Wikipedia says "Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces."

How big is Solar Space?
</h3>
<h4>
According to the article It took centuries,but we now know the size of the Universe "He thought, correctly, that there were many other galaxies as big as our own spread throughout the Universe. But, interestingly, his starting point was a belief that the Milky Way was far smaller than Shapley had calculated." This means that Shapely's calculations were too big so therefore wrong. The milky way is a little smaller than Shaply had calculated.
