Comment on Show HN: Galactic Compass – an app that points to the galactic centerparent

Comments

It would a lot of decimals... the diameter of the Earth's orbit is only 0.0000316 light years, and it's oriented fairly oblique to the galactic center, so the distance changes by only a fraction of that (roughly cos(40°).)

Of course, that's precisely what would make it entertaining!

But also interesting to see whether the number is increasing or decreasing at any given moment.

Of course, upon further reflection I realize that the rate of change is almost entirely determined by the position of the solar system in its elliptical orbit around the galaxy, and speed of the earth's elliptical orbit around the sun, and (at certain occasional points) your position in the rotational movement of the earth.

Anything using the accelerometer would be silly to include...
