Earth Is Drifting Away From The Sun, And So Are All The Planets
Forbes ^ | 1/3/19 | Ethan Siegel

Posted on 01/04/2019 12:07:50 PM PST by LibWhacker

On January 3rd, 2019, Earth reached the point in its orbit where it's at its closest approach to the Sun: perihelion. Every object orbiting a single mass (like our Sun) makes an ellipse, containing a point of closest approach that's unique to that particular orbit, known as periapsis. For the past 4.5 billion years, Earth has orbited the Sun in an ellipse, just like all the other planets orbiting their stars in all the other mature solar systems throughout the galaxy and Universe.

But there's something you may not expect or appreciate that nevertheless occurs: Earth's orbital path doesn't remain the same over time, but spirals outward. This year, 2019, our perihelion was 1.5 centimeters farther away than it was last year, which was more distant than the year before, etc. It's not just Earth, either; every planet drifts away from its parent star. Here's the science of why.

The force responsible for the orbits of every planet around every solar system in the Universe is the same: the universal law of gravitation. Whether you look at it in terms of Newton, where every mass attracts every other mass in the Universe, or in terms of Einstein, where mass-and-energy curves the fabric of spacetime through which other masses travel, the largest mass dominates the orbit of everything it influences.

Sorry, but I won’t believe this theory unless Algore writes a poem about it.

" That is how all stars end their life. It will still remain hot enough to fry planet earth."

A centimeter? Concerning bodies as big as the sun and Earth? With the earth in an eliptical orbit?

Extraordinary claims require extraordinary evidence. They are going to need to show me their work. They can’t just make the claim.

I’ve learned that in modern times we know a lot more than we did in the past and many of the things we knew in the past has been discovered to be dead wrong. Thing is, the past used to be “modern times”. So I see science of today from the lens of a thousand years from now. I see it as wanting and I don’t fully trust it.

“I see where the earth will be fried to a cinder in 5 billion years.”
“Oh, no! We’re all gonna die!”
“Relax, five billion years is a long time.”
“Billion? Whew. I thought you said MILLION.”

But, but but - it’s almost two thirds of an inch EVERY YEAR... the horror.
