Everything is not what is happening on this app, everything is a theory.
The history of our solar system is a puzzle we are still solving. We present the most compelling scientific models.
4.6 billion years ago, a massive cloud of gas and dust collapsed to form our Sun, the heart of the Solar System.
Right after the Sun formed, a neighboring white supergiant exploded in a massive supernova, seeding our system with heavy elements.
Jupiter's early migration through the inner system acted like a wrecking ball, destroying or flinging away many newly formed worlds.
In the early years, Jupiter's immense gravity acted like a cosmic catapult, flinging planets across the stars.
A molten Earth was struck by the planet Theia. From the burning debris, our Moon slowly coalesced.
The theoretical planet Vulcan, once thought to orbit closest to the Sun, spirals inward to its final, fiery end.
Neptune intercepted a binary pair, flinging one member away and capturing Triton into its unique retrograde orbit.
Boreas, an ancient world, crashed into Uranus with such force that it tilted the ice giant permanently on its side.
Once a world of vast oceans, Mars lost its magnetic field, letting the solar wind strip away its water and atmosphere.
Venus was once Earth's twin. A runaway greenhouse effect boiled its oceans into space, leaving a scorched wasteland.
A massive collision with a dwarf planet spun Haumea so fast it became oval-shaped, leaving a red spot at its equator.
A colossal impact with a dwarf planet left Pluto with its most famous feature: the Tombaugh Regio, a bright nitrogen-ice heart.
The planet Phaeton was shattered by a massive asteroid collision, leaving behind the Asteroid Belt between Mars and Jupiter.
100 million years ago, Saturn pulled its moon Chrysalis past the Roche limit, tearing it apart to create its iconic rings.
An asteroid, slingshotted by Saturn's gravity, slammed into Mimas, creating the massive Herschel Crater that gives the moon its iconic 'Death Star' look.
Pan, orbiting within the Encke Gap, swept up ring particles to form its strange, disk-like ridge, giving it the appearance of a space ravioli.
A collision in the Saturnian system left Iapetus with a massive mountain range exactly along its equator and its distinct dark-and-light dual tones.
Callisto's surface is one of the oldest in the system, scarred by a relentless bombardment of asteroids that left it covered in bright impact points.
66 million years ago, Juno slingshotted a massive asteroid toward Earth. The impact at Chicxulub forever changed the course of life on our planet.
In 2005, a comet hit Rhea, creating a faint ring system. However, Saturn's massive gravity is slowly pulling these rings away from the small moon.
