Icy Worlds and the Search for Planet 9, Astronomers ARE on the BRINK of a Major Discovery in 2023

In January 2015, a team of astronomers from the California Institute for Technology (Caltech) stumbled upon a potentially groundbreaking discovery. The alignment of several of the most distant worlds in our Solar System seemed to all have the same perihelion, or closest point to the Sun. This suggested that something big had to have pulled them into these orbits, and flung them out hundreds of times the distance between the Sun and Earth.
All this suggested a roughly Neptune-sized world so distant that it hadn’t ever been spotted. Caltech astronomers Konstantin Batygin and Michael Brown dubbed it Planet Nine. This hypothetical planet may have a mass that's about 10 times that of Earth and orbit about 20 times farther from the Sun than Neptune, the eighth and farthest known planet from the Sun. Planet Nine may take between 10,000 and 20,000 Earth years to complete one orbit around the Sun, according to NASA.

There is absolutely not a 1 in 10 chance of a violent collision between a space probe and an asteroid while transiting the asteroid belt. Not even close.

Jumping into hyperdrive requires careful calculation.

[@misterflibble6601]

More like 1 in a _billion_ so yeah. And I don't think Jupiter has an athletic center. Careless errors that spoil the video for me.

[@JimKrause1975]

This is why I don't agree with people who say they think we are alone in the universe. We can't even find planet 9 or planet X. Maybe we are the only life in this part of the galaxy or the solar system. We are seeing a lot with our amazing technology. But there is still even more that we have not seen and we know nothing about. Dark matter and dark energy are perfect examples. We are still not sure what they are. We just know something is holding galaxies together and something is causing space to expand. I love this channel! My favorite place to learn about my favorite topics!!

I appreciate your hard work on these videos ❤

The synthetic person says ur welcome

Good, non political science that emphasizes that these are "theories" and more information is still needed :) keep it up!

1:03:08 What? Earth spins around the sun every 74,000 years as opposed to 18,500 years?

I love these videos.

Well done 👍🏻

[@TVQuantumUniverse]

Thank you 😁

[@chadsheldon6470]

I hope whatever alien civilization comes across the Voyager probes has a record player to listen to the golden record we sent with them.

[@cbly]

Or at least instructions on how to build one.

[@whirledpeas3477]

And speakers 🔊

[@garrettalexanderfoote3411]

They put a record player with the golden record with the instructions to play it with it

[@NotLazySelectivelyMotivated]

They’ll build one and Voyager will have started a whole new intergalactic industry. That’s assuming they have senses like ours. 😂😂😂😂

[@ijustwanttolikecomments4677]

@@whirledpeas3477 instructions for all those things are etched onto the record, including what speed to play it at.

Take it as a compliment if someone travels 150 million kilometers in order to get a closer look at Uranus.

How do we know that there are exoplanets light years away, yet we don’t know whether or not there is a ninth planet in our own solar system?

[@brograb898]

Light and gravity. If you have a flashlight behind you and you are looking into the darkness away from it, it’s very dark. Even points of light (stars) thousands of light years away provide both gravitational signals or transit signs of exoplanets.

[@agluebottle]

All the exo planets we've detected have been very close in to their host stars. To my knowledge, we still haven't been able to detect any with orbits as wide as Saturn's. Any planet 9 would be something like 10x as far from the sun making it both incredibly dim and incredibly slow moving. Remember, it took all of human history until the 1920s to find Pluto.

[@hughjarse8944]

@@agluebottle Yes. Thanks.

[@nickbrockelman]

@17:08 you mentioned the particle size of the Rings of Saturn but say they're from the Earth.
Then again same mistake @17:45 by saying an ice Moon approaching Earth instead of Saturday

[@jorgensvensson5257]

Saturn?

An ice moon on a Saturday? Guess I have to cancel my weekend plans 😕🥶
