The worlds around us
The sizes of some of the objects in space are huge. So huge it is difficult to us to comprehend exactly how large they are. Here are some images that may help show the difference in sizes.
My god, is Antares big enough to occupy the entire orbit of the Earth? It's interesting how Venus is so much closer in size to Earth than Mars is. Everyone talks about settling Mars, but wouldn't settling Venus be more practical because of similar gravities?
Antares is BIG. Its radius is about 800 times bigger than our Sun. If you put it in our solar system, the outer surface would be between the orbits of Mars and Jupiter. Venus is certainly closer in size to Earth and gravity, but it is blanketed with clouds of sulfuric acid. The atmosphere is extremely dense (92 times that of Earth) and composed of mostly carbon dioxide. The cloud cover generates the strongest greenhouse effect in the solar system causing surface temperatures over 860 °F. I wouldn't want to be there. Florida is hot enough for me.
