At first I set the simulator to show 0.5 degrees, because this is about the apparent size of the Moon in our night sky, but then I realized that is setting the image at that size(the image size would equaled the same size that the full Moon does- not what I want)

So I set the simulator to view the Moon from the Earth and adjusted the size to about what the moon looks like in our sky. It was at the 10 degrees. So I used this same setting for my two views. If I am close, then you can see Jupiter’s 4 large moon with the necked eye from the surface of Mars. You might even be able to make out Jupiter’s disk.

Another view I would love to see is Earth and Venus from Mars.

I wonder how bright the Earth is as seen above Venus clouds during their closet approach? And can the Earth’s disk be seen? From our vantage point, Venus is very bright despite being a thin crescent. If we could see a fully lit Venus during the closet approach, I bet it would rival the Moon in brightness.

The last two view I am curious about is seeing Venus and Earth in Mercury’s sky, and what Jupiter and Saturn look like to each other during their closest approach.

Thanks for your insight. Our culture might have been different if we had closer view of Jupiter.

I wonder how fast the science of Astronomy would develop to a society who lived on a world that orbited a gas giant?
