Star Stroll

Take a stroll through an interactive map of nearly 120,000 stars in our local galaxy with information on almost 600 exoplanets.

Stars are continuously loaded as you traverse the sky. The visible distance may be set on the first screen (be aware that raising this may cause performance issues).

The projection of the map can be changed between 3D and 2D. In 2D, the map can be shown as either the flattened galaxy or a representation of distance from the sun (called RA_DIST herein). Tap on stars to move through the galaxy and discover new places.

Each star has its own information which includes at present: luminosity, spectral type, distance from the sun, constellation and any known planets. Planet information includes their mass, orbit radius, orbit period and eccentricity of orbit.

The data for this app was acquired from (and many thanks go to) the HYG catalogue (www.astronexus.com) and the Planet Habitability Laboratory (phl.upr.edu).
