Stars in Your Pocket: Astronomical Geekery for SFR writers
By Christie Meierz
If you’re writing a romance set long, long ago in a galaxy far, far away, you don’t need to know the names and locations of our local stars. You can make up your own stellar neighborhood, within certain constraints. Set your story in nearby space, however, and the route you take in order to get from one star to another could end up resembling a trip from Philadelphia to Boston—via Los Angeles. Someone will throw your book across the room.
You can explore the US eastern seaboard to your heart’s content, or you can talk to someone who’s lived there, but no one’s ever actually been to Alpha Centauri, or Tau Ceti, or Beta Hydri. So how do you put the stars in the right places, much less keep them all straight in your head? It’s not as hard as you think. Here are a few resources I use.
Hands down, this is my favorite toy to play with when I need to get a feel for where something is in the sky—but it comes with a caveat: it only works with a narrow range of outdated versions of Java. I get around that by using a different browser than usual (Internet Explorer), never using it for anything else, and never updating it.
What 3D Galaxy Map does is let you break down the Milky Way galaxy into manageable cubes, 10-parsecs to a side. The default starting location is centered on our sun. Play with it for a little while, and you begin to get a feeling for where the named stars are in relation to our sun and to each other. You find out that stopping at Tau Ceti on the way from Earth to Epsilon Eridani makes sense, but stopping at 61 Cygni on the way to Delta Pavonis… really doesn’t. Once you get comfortable with the local neighborhood, move one sector over—I moved outward—and start getting to know that neighborhood. Hello, Capella!
It’s fun. Really!
This plain text, utilitarian site will tell you more than you ever want to know about any star in its database, which seems to be every catalogued star in the sky. I use it to calculate distances, because if you’re looking at stars less than 25 light years apart, it’s a great timesaver. Want to find out how far Delta Pavonis is from Beta Hydri? Just look up either star in the database, and right at the top of the page, there’s a button that says, “Find all stars within” and an input box with a default of 15 light years.
Caladan and Tolar are 9.3 light years apart. And see? I didn’t have to do the math.
All right, now you know the local stars. Which ones have planets where your romantic characters can make love under an alien moon? None of the sites you’ll find are particularly friendly to the non-scientist, but Wikipedia’s is probably the least intimidating.
Here you’ll find a short list of the likeliest candidates, with Earth, Venus, Mars and Mercury thrown in for comparison. Warm mesoplanets similar to Earth have helpful green labels under the hClass column. You can sort by any column; I find sorting by distance most useful.
If you’re hardcore, go here. Everything is there. Everything.
Future technology can cover a multitude of errors. I chose Beta Hydri for my planet based on outdated information, and then someone pointed out to me that the star is veering off the main sequence, making it a bad candidate to host a habitable world. A planet in the habitable zone, the narrow band around a star where liquid water can exist on a planet’s surface, must be there long enough to evolve complex forms of life (like plants). Such a planet circling Beta Hydri would be boiling now, as the star has heated up and the habitable zone has moved farther out. No problem! I put a planet in the current habitable zone and terraformed the heck out of it. In a few hundred million years, Tolar will be boiling too, but I only need 6,000.
You don’t need to know everything, but knowing your way around the neighborhood is part of setting the scene. We live in a fairly nice little bubble of the Milky Way galaxy, blasted almost clean by ancient supernovae (think of it as urban renovation on a BIG scale!). Take a look around. Get to know the place. You’ll be glad you did.

About The Fall
As bitter enemies scheme against each other with the fate of Tolar in the balance, Laura Howard, made a powerful empath by the Jorann’s gift, loses everything—again. Now she must recover and find her place, and herself, while fighting against the ghosts of her past and the expectations of everyone around her.
Loss after tragic loss shakes the Paran to his very soul. With his allies vying for control of the planet and his own province caught in the middle, he must risk his life as well as that of the woman he loves to take the one action he never thought he would: fight for leadership of the ruling caste.
