For those who prefer knowing to wondering, there are numerous apps that can help make sense of the celestial scene. Stars and distant planets glitter in the early morning sky and return each evening before dinner, providing ample opportunity to look up and wonder. If there’s a bright side to the lengthy darkness of winter, I’d say it’s the much-expanded opportunity for stargazing. No copyright issue is too small.This screenshot shows how the Ursa Major constellation appears in the Stellarium app (set to Western culture), with a few bright stars also identified. If you have issues with any assets or resources in Graviton, please don't hesitate to reach out DJBen. (?) A space flight simulator that utilizes patched conics approximation.An educational astronomy app with science in mind.A full-fledged open source stellarium software.As a lover of science and space exploration, there are a few long-term goals: This is an amateurish project by an amateur astronomer. To account for apsidal precession and other orbital perturbations of celestial bodies like Mercury and Earth's moon, Orbits fetches many data points from JPL and cherry-pick the orbital configuration closest to the reference time. Support querying rise, transit and set timestamps for major celestial bodies.Ĭonics model predicts the orbits of the major planets in our solar system pretty accurately.Stock ephemeris from 1500 AD to 3000 AD of major celestial bodies. Query and process high accuracy ephemeris from NASA JPL's Horizon interface and automatically cache results using Realm and SQLite.Calculate Keplarian orbital mechanics with support of all conics.High accuracy ephemeris query and orbital mechanics calculation framework. One includes all documentation, the other is a shiny front page for maximum appeal. Rise, transit and set time of the sun, the moon and all planets.Astronomic properties including Julian date, LST offset and more.Goes forward in time to see the motion of heaven.Browse the celestial object catalog, search the desired celestial objects and inspect their physical properties.Time warp to any time in the past and future to view the predicted night sky.Find the constellations and solar system plants. View the simulated night sky at your local position and local time.FeaturesĪctive development in progress features will change without notice. The appearance of stars will appear like squares instead of round dots. There's an issue that iOS 11.2 breaks SceneKit transparency texture. That's all you need for bootstrapping! Now you can proceed to open the Xcode project file.
