Solar System Simulation SSR. Android globus coelestis (celestial globe) and interactive calendar with Zodiac signs and timepiece covering the Solar System in the entire observable universe up to $r=14.25Gpc$ (c.f. the_great_debate_1920).

Contains $n=69$ stars, $n=70$ nebulae and star clusters, most important Milky Way objects, $n=48$ galaxies and galaxy clusters (c.f. galaxies_tab) as well as the most well-known quasars. Full implementation of all $n=110$ Messier objects M (Messier, 1784), Inner Cloud (Hills, 1981), Oort Cloud (Oort, 1950) and more.

Further astronomical objects can be implemented by means of external definition files (ssr_*.dat). All objects of the Caldwell catalogue C (Moore & Pepin, 1995) as well as parts of the Herschel 400 catalogue (Mullaney, 1976) are included as ssr_Caldwell.dat and ssr_Herschel400.dat, see further ssr_orion.dat, ssr_local.dat, ssr_IC342_Maffei.dat and ssr_gw__.dat. For additional important astronomical catalogues see e.g. CN (Herschel, 1786), NGC (Dreyer, 1888), CGCG (Zwicky et al., 1961) or PGC (Paturel et al., 1989).

Solar System parameters of the Sun, planets and Moon are based on the current NASA Planetary Fact Sheets (Williams, 2025). Positions, distances and sizes of further objects are from Wikipedia sources (Wikipedia contributors, 2025), which can be traced back primarily to the SIMBAD astronomical database (Strasbourg astronomical Data Center, 2025), the VizieR Catalogue Service (see Ochsenbein et al., 2000) or the NASA/IPAC Extragalactic Database NED.

Object distances $r$ in parsec $pc$ are calculated from parallax $\pi_{O}$, given in milliarcseconds $mas$ with

$$r=(\frac{\pi_{O}}{1000})^{-1}, \pi_{O}=1000\cdot r^{-1}.(1)$$

The luminosity distance $r=d_l$ in parsec $pc$ is given by

$$r = 10^{\frac{\mu}{5}+1}, \mu=\frac{5\cdot\log(r)-5\cdot\log(10)}{\log(10)}(2)$$

with distance modulus $\mu$, defined by the difference between apparent magnitude $m$ and absolute magnitude $M$ as

$$\mu = m-M.(3)$$

Object radii $r_{O}$ at a given distance $r$ are calculated via angular diameter $V°$ where

$$r_{O}=r\cdot\tan\frac{V}{2},r=r_{O}\cdot(\tan{\frac{V}{2}})^{-1},V=2\cdot\tan^{-1}\frac{r_{O}}{r}(4)$$

with

$$V=\frac{V°}{180}\cdot\pi, V°=\frac{180\cdot V}{\pi}.(5)$$

For more on photometry see e.g. Miles (2006) or Milone (2011), c.f. also Schrausser (2025) and EM_field.

In addition, the following calculations can be performed: Given value $x$ to (a) speed of light $c$ in $\frac{m}{s}$ and to (b) astronomical unit $AU$ in $km$. Furthermore, parallax $\pi_O$ in $mas$ (1) to parsecs $pc$, Modulus $\mu$ (3) in $mag$ to parsecs $pc$ and parsecs $pc$ to light-years $ly$. Conversions can be performed for (a) hexagesimal degrees ° or hour $h$, $min$, $sec$ to decimal degrees °, (b) angular degrees ° to radians $rad$ and (c) angular diameter $V$ (4) in degrees ° for a given distance $d$ to radius $r$.
