Helical model solar system nasa

What does the helical model feel like?

The helical model feels much more like progress, growth, a journey through space in which we never ever come back to our starting point. We are NOT in a big marry [sic]-go-round. We are on a journey.” Planets trace a helical path in space because our Solar System is orbiting the center of the galaxy. Big bloody deal. It’s that simple.

Does the Solar System make a vortex shape?

There are literally trillions of large masses in our Solar System, all orbiting around the galactic center on timescales of hundreds of millions of years. But there's a viral video, parts 1 and 2, that claims that as the Solar System moves through the galaxy, it makes a vortex shape, pulling the planets behind it as it does.

Do planets trace a helical path in space?

Planets trace a helical path in space because our Solar System is orbiting the center of the galaxy. Big bloody deal. It’s that simple. You don’t need a wacky alternative model of the Solar System for this – it’s happening anyway! As for going on a journey though – well no, not really.

Is a vortex a helical path?

A vortex is not a helix. Nowhere was the definition of a vortex provided in the context. While planets do trace a helical path as they move through the galaxy, this is not evidence of a vortex. Yes, the sun actually is moving through space, as it traces a path around the center of the galaxy.

What is the difference between helical motion and a vortex?

Plait notes: “They’re different in more than just name; they’re actually very different physical motions with different properties—you can get helical motion without the particles in it interacting, like in the solar system, but in a vortex the particles interact through drag and friction.”

Are all planets visible in a heliocentric model?

“Secondly, most planets are visible throughout the entire year. In a ‘flat’ model, every single planet would hide behind the Sun at least once a year. They don’t. Now the heliocentric model isn’t entirely flat, but mostly.” Fine. The heliocentric model isn’t flat, which perfectly explains why planets aren’t eclipsed by the Sun once per year.
