The Physics of Reddit's Spinning Solar System Icon | WIRED

In order to see if this figure moves in some type of realistic way, I need to look at the motion of the planets. One of the simplest things would be to look at the angular position as a function of time. What is the angular position? If you were to draw a line from the middle of the center sun to one of the orbiting planets (in a flat plane), the angle between this line and the x-axis would be its angular position.

From the video analysis, I get the following data for the angular positions (in units of radians) of the inner and outer planets.

Gas giant exoplanet with weirdly long orbit may bear clues about our solar system | Space

Scientists have managed to measure both the size and orbit of a gas giant exoplanet nearly 1,300 light-years away from Earth. Dubbed GOT 'EM-1b, which stands for Giant Outer Transiting Exoplanet Mass, the planet is roughly five times the mass of Jupiter .

Usually scientists struggle to measure the size of giant gas planets , like Jupiter and Saturn, because they're far away from the stars they orbit. Yet, this planet showed up in what researchers call our "solar neighborhood" in 2010, when NASA's Kepler space telescope first discovered the object. Astronomers then noticed periodic decreases in the brightness of a nearby star, called Kepler-1514, which clued the researchers in to the possibility of orbiting planets.

Solar System History 101 | The Planetary Society

Our solar system is a wondrous place. Countless worlds lie spread across billions of kilometers of space, each dragged around the galaxy by our Sun like an elaborate clockwork.

How did our solar system come to be? Why are these objects where they are now? Here is the series of events that made and shaped our solar system, to the best of our knowledge, pieced together from space missions, Earth-based observations, and complex simulations by scientists trying to figure out our place in space.
