SkyORB 2020, Astronomy in AR, Skygazing, News | realtech VR

SkyORB is more than a simple star map, it's a collection of 7 tools including a 3D star map, 3D planetarium, ephemeris, search engine, sun clock, point to sky, weather, and more. SkyORB is the 3D astronomy App for the Mac, iPhone, iPad, Apple Watch, Android and Windows Store

“SkyORB is fantastic for anyone interested in the night skies, but it’s not just a star-gazer’s handbook.“ - ★★★★

“We love SkyORB because it not only offers 3D images of the planets and the stars in the sky, along with comets and asteroids, but it also comes a 'point to sky' feature that allows you to aim your handset towards a star or planet and it'll identify it for you“ . - PC Advisor: Best iPhone apps: Five free apps for astronomy ★★★★★

Current version is 2021.3 

What we've added so far since the beginning of the year:

- Extensive Meteor Showers database with exact time of peak day
- Mac version now uses Metal API (Metal API is coming for iOS 13).
- Stereographic skychart on iOS Today Widget, Apple Watch and in application.
- Jovian events
- Supports for iOS 12 notifications, ARKit, Spotlight search and more
- Redesigned sun graph (times of daylight, night and twilights), sun clock and added year sun graph. Sunset and twilight times are now improved in accuracy.
- Super high definitions textures with ASTC compression for mobile.
- Exact time of solar and lunar eclipse based from your location.
- And much more!




SkyORB features many functions as a 3D real-time representation of the planets position around the sun, the ability to hold your device and point toward a visible star and planet and reveal the name by tracking the GPS position, compass orientation, the elevation from the gyroscope, warn the user when a phenomenon is occurs as a full moon, a planet really visible, which is worth the observation.

SkyORB is *free* of charge and you can upgrade to the premium version directly from the application to enjoy even more features, as notifications and on-the-cloud backup. What you will get with SkyORB (Lite version):

• a 3D real-time planetarium with photo-realistic rendering, different views like real position, false scale, lined-up and exploration.
• a 3D real-time sky rendering, with tracking from compass and gyroscope,
• Comets and satellites positions, with update from the Web for latest entries,
• Satellites ground location
• Comets orbit chart
• A slider to explore from the solar system up to the milky way. 3D star chart view.
• iOS 14 widget, with sky chart available at the home screen
• Apple Watch support with equation of time, realtime sky chart
• Weather forecast from current location,
• Jovian events : Display jupiter majors moon position as seen from a telescope, and time of events.
• Ephemeris including next 60 days astronomy events, including peak day of meteors showers, date of planet elongation and opposition.
• Display day/night terminator on a world map,
• Powerful universal search engine: type few letter and find a matching nebula, constellation, place, planets, exo-planets and more.
• Moon phases with dates, including rise and set times,

Q: How to reset the time shift in the app?
A: If you use a phone, you can quickly shake the phone, it will vibrate and the time-shift will be reset to the normal date

Q: How to force in English?
A: Only on iPhone, you can change this settings from the System Settings, SkyORB

Q: How to change the location on Mac or Windows?
A: You can use the location for automatic, but if it is not accurate, uncheck the 'automatic location' and click on the colored longitude and latitude values

Q: What is the value display on the Apple Watch complication?
A: The value is the equation of time. Found on some watch, this shows the difference between "true" solar time (that of Nature) and "mean" solar time (that of Man). This rare and poetic complication is usually combined with other astronomical indications. See this article

Q: How to reset the time shift in the app?
A: Time shift allow to go back or forth in the time. If you use a phone, you can quickly shake the phone, it will vibrate and the time-shift will be reset to the normal date. Else press the 'Now' button again when your are in the time-shift

Q: How to search with the Apple Watch
A: Open the app from the Apple Watch and hold press, then you can speak out the word like Where is the Moon, Where is Mars etc..


iPad App Reviews

 Considering that SkyORB is a free app, it's breadth of functionality may have you convinced you'd paid a couple of dollars for it. SkyORB is fantastic for anyone interested in the night skies, but it's not just a star-gazer's handbook. Not only do you get wonderful interactive maps and plans of the night skies but SkyORB also takes you on journeys through the solar system. The defining feature of SkyORB is its 3D functionality. Night-sky images as well as those from the solar system can be manipulated in 3 dimensions, showing how our wonderful solar spheres co-exist and interact.

App Advice

SkyORB is a decent stargazing application that utilizes a really good digital compass and a 3D interface. It lets you search and find stars, deep sky objects, current satellites and shuttle missions, and enables you to see the sky from any point on earth. The trial version is of course free but is stripped down in features, unless you pay for the premium version for a few bucks right inside of the app.


Glossary and terms used in SkyORB




Right ascension (abbrev. RA; symbol α) is the astronomical term for one of the two coordinates of a point on the celestial sphere when using the equatorial coordinate system. The other coordinate is the declination.

Declination (abbrev. dec or δ) is one of the two coordinates of the equatorial coordinate system, the other being either right ascension or hour angle. Dec is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of the celestial equator.

The Minor Planet Circulars (MPC): The Minor Planet Center, under the auspices of the International Astronomical Union, it is the official organization in charge of collecting observational data for minor planets (asteroids) and comets, calculating their orbits and publishing this information via the Minor Planet Circulars.

TLE or Orbital elements are the parameters required to uniquely identify a specific orbit.

Opposition : A planet (or asteroid or comet) is said to be "in opposition" when it is in opposition to the Sun, as seen from the Earth. When a planet is like this,

  • it is visible almost all night, rising around sunset, culminating around midnight and setting around sunrise;

  • at this point of its orbit it is roughly[1] closest to the Earth, making it appear bigger and brighter.


Aphelion: A planet is said to be farthest distance from Earth.

Perihelion: A planet is said to be closest distance from Earth. The planet will appear bigger and easier to spot.
