Current version: solar system simulation v_2.9 (5 Nov 2026)

This simulation is for scientific and educational purposes. It is also a support software for the book "Marea greșeală a „marelui” Einstein" by Ovidiu Bidian (Artpress, ISBN 978-973-108-587-6).

What is real in this simulation:

• the motion of the Sun through absolute space, as science sees it today (2026): the Sun moves around the center of our galaxy, the Milky Way, on a huge orbit with a radius of about 26 000 light years, at about 230 km/s, one turn in about 230 million years. It moves towards the constellation Cygnus, at about 60° to the plane of the planets' orbits (the ecliptic), so the trails leave that plane at this angle. The absolute space of this simulation is a cylinder around the Sun's path. In this simulation the time frame of absolute space is about 165 years (one revolution of Neptune: the trails need that long to reach the wall of the space), so the path of the Sun through absolute space is a straight line. The trajectories of the celestial bodies through absolute space are represented by their yellow trails;
• the orbits of the celestial bodies (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto) around the Sun: real orbital elements (JPL, epoch J2000), real periods, real sizes of the celestial bodies;
• the orbit of the Moon around the Earth: the mean lunar elements (the orbit turns: its node once in 18.6 years, its perigee once in 8.85 years) and the main disturbances by the Sun (Meeus, from ELP-2000/82), within about 2 arc minutes (some 200 km) of its real place; the Moon always shows the same face to the Earth;
• the motion of the planets on their orbits obeys Kepler's laws;
• the rotation axes of the celestial bodies: real directions in space (for example Pluto's axis is tilted about 120° from the axis of its orbit, so Pluto spins backwards); the views around a celestial body use its real equator and rotation poles;
• the surfaces of the celestial bodies: real maps (Pluto: NASA / JHUAPL / SwRI, New Horizons; Mercury, Venus (its clouds), Earth, the Moon, Mars, Jupiter, Saturn and its main rings, Uranus, Neptune: Solar System Scope);
• the light: the celestial bodies are lit by the Sun, from the center of the Sun; the Moon's shadow on the Earth (eclipses of the Sun) and the Earth's shadow on the Moon (eclipses of the Moon), with umbra and penumbra; in the Earth's shadow the Moon is copper red, lit by the sunlight that the Earth's atmosphere bends into it.
• the constellations: the real directions, brightness and colours of their stars (Hipparcos catalogue, J2000, through d3-celestial by Olaf Frohn), with their names. Among them those from which the motion of the Sun was found: Hercules (the solar apex, found by Herschel in 1783 near lambda Herculis from the motions of Sirius, Castor, Pollux, Procyon, Regulus, Arcturus and Altair), Lyra (Vega, near the apex), Columba (the antapex), Cygnus (the direction of the Sun around the center of the galaxy), Vela (the opposite direction) and Sagittarius (the center of the galaxy, whose motion on the sky gives the speed of the Sun, about 230 km/s).
• the Milky Way: the glow of our galaxy's disk, as seen from the Earth on a dark night, from a real map (Deep Star Maps 2020, NASA Goddard Space Flight Center, Scientific Visualization Studio, from the Hipparcos, Tycho and Gaia catalogues), in its real place on the sky: brightest towards Sagittarius (the center of the galaxy), with its dark dust lanes; it is dimmed, so that the constellations remain easy to read.

What is not real in this simulation:

• the background stars: placed at random, with random brightness (the stars of the constellations are real);
• the look of the Sun: its surface (granules, sunspots, faculae) and its explosions (flares, prominences, coronal mass ejections) are drawn by the program, much faster than in reality (in screen time, as the spin of the celestial bodies); they show what the Sun looks like, not what it does on a given day. The prominences are pink as seen through a hydrogen-alpha filter (in white light they are seen only in a total eclipse);
• the spin of the celestial bodies: every celestial body turns once every 10 seconds, at every simulation speed (Pluto really turns once in about 6.4 Earth days);
• the apparent size of the celestial bodies: a minimum apparent radius is set, so that a celestial body can be seen also from far away;
• the brightness of the Moon in a total eclipse: shown as the eye sees it, adapted to the dark (in reality it is some 10 000 times fainter than the full Moon);
• the dark side of the celestial bodies: lit a little, as the Earth's night side by a full Moon, so that its surface can be seen;
• in the Moon locked view the Moon is drawn as large as the Earth, and in the Earth locked view the Earth as small as the Moon, so that the Moon's phases and the Moon's face turned to the Earth can be seen (their places, paths, light and shadows stay real);
• the shape of the celestial bodies: drawn as spheres with their mean radius (Saturn is about 10% and Jupiter about 6% flatter at the poles); the faint rings of Jupiter, Uranus and Neptune are not drawn;
• the celestial bodies move on independent orbits (they do not attract each other); only the Sun, the planets, Pluto and the Moon are shown (no other moons, no asteroids or comets).

This software was made by Claude Code under the direct and close requirements and supervision of a human, Ovidiu Bidian.
And no, AI will not kill us all by 2030 — human stupidity might.
One (important) note: the term "artificial intelligence" is not correct; it should be replaced with "artificial thinking", because this is what AI actually does.

Enjoy the simulation!
