About
Solar 5195
An interactive 3D simulation of our Solar System, built for anyone curious about space. Every planet is positioned using NASA JPL Keplerian elements, accurate from 1800 to 2050. The Moon follows the ELP2000 analytical theory by Jean Meeus. Set the date to any day in history and watch the cosmos align.
Solar System
Eight Planets, One Star
Our Sun holds 99.86% of the Solar System’s mass. The inner rocky worlds — Mercury, Venus, Earth, Mars — are dwarfed by the gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune. Beyond Neptune lies the Kuiper Belt, home to Pluto and countless frozen remnants of the early Solar System.
Click any planet to see its real data. Advance time to watch orbital mechanics in action — Mercury completes a full orbit in 88 days, while Neptune takes 165 years.
Historic Missions
Humanity’s Greatest Journeys
Five iconic missions are traced in the Solar System view, and three can be explored from Earth orbit. Each trajectory uses real launch dates and planetary positions.
🚀
Apollo 11
The first humans on the Moon. Armstrong and Aldrin walked the Sea of Tranquility while Collins orbited above.
LaunchedJul 16, 1969
ObjectiveFirst human lunar landing
StatusCompleted (8 Days)
🛸
Voyager 1 & 2
The Grand Tour. Voyager 2 visited all outer planets. Voyager 1 is the most distant human object (165+ AU).
Launched1977
ObjectiveExplore Outer Solar System
StatusStill Active in Interstellar Space
🪐
Cassini–Huygens
13 years orbiting Saturn. Discovered ocean worlds on Enceladus and landed on Titan.
LaunchedOct 15, 1997
ObjectiveStudy Saturn and its moons
StatusCompleted (2017)
💫
New Horizons
The fastest probe ever launched. Gave us the first close-up images of Pluto’s heart-shaped glacier.
LaunchedJan 19, 2006
ObjectivePluto flyby & Kuiper Belt
StatusActive in Kuiper Belt
Earth Orbit
From Our Doorstep to L2
Switch to Earth Orbit to see our planet in high-definition with real-time Sun illumination and an accurate Moon position. Three missions can be replayed from launch:
🌙
Apollo 11 (Earth View)
Watch the trans-lunar injection arc from Earth to Moon and the return trajectory.
LaunchedJul 16, 1969
ObjectiveEarth-Moon Transfer
StatusCompleted (Auto-pauses)
🏹
Artemis I
NASA’s 2022 uncrewed test flight featuring a Distant Retrograde Orbit (DRO) far beyond the Moon.
LaunchedNov 16, 2022
ObjectiveTest SLS & Orion
StatusCompleted (25.5 Days)
🔭
James Webb Space Telescope
Orbiting the Sun-Earth L2 point, 1.5 million km away. Its halo orbit takes 6 months to complete.
LaunchedDec 25, 2021
ObjectiveObserve early universe
StatusActive in L2 Halo Orbit
💡Tip: Use the speed controls to fast-forward through decades. Try clicking a planet, then pressing “Follow Mission” to lock the camera on a probe as it traverses the Solar System. Hit “Today” to jump back to the present.
