Astronomers Just Found a New Dwarf Planet That Is Three Times As Far Away As Pluto

“Far Out!”

It’s official: astronomers found a new dwarf planet in our solar system — and it’s the most distant object ever observed in our solar system.

I said ‘far out!’ when I discovered it, and it’s a very far out object,” said astronomer Scott Shepard from the Carnegie Institution for Science.

The tiny planet is called 2018 VG18 — later nicknamed “Farout” by the team that discovered it — and it’s about 3.5 as far away as Pluto, some 18 billion kilometers (11.2 billion miles) away.

That’s more than 100 times the distance between the Earth and the Sun — and about the same distance as Voyager 2, the NASA probe that launched in 1977 and reached interstellar space this month.

Farout was spotted by the Japanese Subaru telescope in Hawaii on November 10 by Shepard and several colleagues, according to a statement on Carnegie Institution for Science’s website.




Unusual Orbits

So far, Farout is still deeply mysterious. But one aspect already attracting scientific interest is its unusual orbit. Farout orbits at an unusual angle, along with other so-called “trans-Neptunian objects.”

There’s been a lot of speculation in recent years about what might be causing those astronomical bodies’ unusual trajectory.

One of the most popular explanations is the possible existence of a ninth planet, or Planet X. In fact, the astronomers discovered Farout while searching for the existence of a ninth planet, according to the statement.

Most recent data suggests it could also be a group of objects within the same gravitational field.

Slow and Pinkish

But we can glean at least some details about Farout. Farout is estimated to be 500 km in diameter, and to take more than 1,000 years to orbit the Sun. It also has a pinkish hue, according to the researchers.

With new wide-field digital cameras on some of the world’s largest telescopes, we are finally exploring our Solar System’s fringes, far beyond Pluto,” said Chad Trujillo, astronomer from Northern Arizona University.

The discovery shows that even though researchers are now routinely finding planets orbiting other stars, there are still planet-sized undiscovered objects in our own solar system.

It really goes to show how much there still is to learn about our relatively small corner of the galaxy.

Have We Found Planet X?


There’s been a lot of noise, especially on social media, about a possible 9th planet being found in the solar system.

Is it real? What’s the evidence? And is this a new thing?

=================

The ancient Greeks only knew about 5 planets: Mercury, Venus, Mars, Jupiter, and Saturn.

Then in the late 1700s, William Herschel used a new telescope technology to find Uranus. But a wobble in its orbit suggested the presence of another planet…

Using this wobble, mathematicians calculated the position of this 8th planet in 1847, and Neptune was discovered. It was the only planet discovered by math.

Today, astronomers have discovered several asteroids from the Kuiper Belt that have very similar elliptical orbits through the solar system that are so close that it is only a 1 in 15,000 chance of happening at random.

And they are using similar math to map the location of a 9th planet, but one that is very different from the ones we know.

This planet would orbit far outside our current solar system and would take 15,000 years to orbit.

Time will tell whether this proposed planet will be found, but scientists studying the phenomenon at the Subaru Observatory in Hawaii believe they’ll have an answer in 5 years.
