One of the best things about writing science fiction is challenging myself to get some of the science right. For Deathform, I'm playing it pretty loose when it comes to human technology, but I want the astronomy to be as accurate as possible. In the early stages of my research, I ran into this little gem, an interactive model of the solar system.
Pretty fun to spin them around and watch the calendar tick away. Grab a hold of Jupiter or maybe one of the dwarf planets and watch the Earth years fly like nothing.
I recommend changing the settings to "realistic." It's not all 100% to scale as far as I can tell, but gives you an idea how tiny these bodies are in the grand scheme of things.
