SkyORB, developed by realtech VR, is a 3D planetarium app for Mac that recreates the night sky to support observation and classroom demonstrations. It renders planets, stars, satellites, and constellations in real time and includes search, event notifications, a moon calendar, and AR identification for field use. The app is designed for amateur astronomers, students, and educators who need location-aware visual models and extended datasets for curriculum work.

The app recreates the sky for hands-on observational study

Real-time 3D rendering produces location-based views of planets, stars and constellations, and the planetarium includes moons, comets, and asteroids. Multiple projection modes are available to match study needs, such as altazimuthal and stereographic. Visual outputs include detailed 3D models and a time-travel feature that shows celestial positions across dates, so learners can compare historical and future skies side by side.

It supports inquiry-led learning with temporal and identification tools

The app provides scheduling and identification features that support guided observation and independent inquiry. Students receive personalized notifications for astronomical events and a moon phase calendar with rise/set times. An AR "point to sky" mode identifies objects by device orientation, and ephemeris and weather forecasts are available to plan observational exercises, reinforcing cause-and-effect between sky conditions and visibility.

Suited to learners and educators, with deep datasets and cross-platform reach

Targeted at amateur astronomers, students and educators, the app includes specialized data for exoplanets and deep-space probes as well as artificial-satellite tracking whose orbital data updates from the web. It runs as a Universal Binary for macOSor later) and is part of a cross-platform ecosystem that keeps study materials consistent across desktop and mobile devices. The developer has maintained the project for over 20 years.

A strong visual teaching tool with a desktop input consideration

The app is a practical option for educators and learners who value richly detailed visual datasets and time-based sky study, because it supports lesson planning and hands-on observation. One consideration is desktop input: some Mac users report the interface leans toward touch interaction, which may require adaptation for mouse-driven classroom setups. Instructors should pair the app with structured tasks to integrate it into lessons effectively.
