    Many Happy Orbits offers graphics, exoplanet ages, and upcoming birthday calculations

    The tool displays your age as a fraction of planetary orbits in a graphic format, calculates next birthday events (Plait's next major one is his sixth Jupiter birthday in nine years), includes ages for asteroids and exoplanets, and features astronomical information.

    “Pretty fun, and I imagine kids would really like this (Countryman's daughter inspired him to create it).”
