Astronomers from all over the world are on the look out for a huge, unexplored world known as Planet Nine, which could change everything we think we know about the solar system.
They have to know that it is there, so its size may be 10 times greater than that of the Earth, and the powerful force of attraction.
However, the Planet’s Nine-show is not to be found, which shows just how much we don’t know what’s going on in our own world in the backyard.
Astronomer Alan Duffy, a Professor of Astrophysics at Swinburne University, said the theory behind the Planet of the Nine only came into being relatively recently, after the Brazilian-stargazer noticed the strange things that are happening at the edge of the solar system.
“The idea is that the orbits of our solar system, it turned out to be surprising behavior can be explained by the gravitational pull of a very large, very distant world,” Professor Duffy said.
In 2012, Rodney Gomes, an astronomer at the National Observatory in Rio de Janeiro, presented his claim that a giant planet could not be seen behind the troubles.
But then how do you explain the existence of a large planet, and without it they will be able to see it or even vaguely pinpoint where it is?
“There is historical precedence here, as this is exactly how we found Neptune,” Professor Duffy said.
The planet Uranus was discovered with the aid of a telescope in 1781, but it raised more questions than it answers, he says.
“Put simply, Uranus was not where it was meant to be,” he said. “It was not in the position to make the calculations, it is shown to have. As the years have passed, science has determined that there has been a greater, or further, a planet that is pulling out of the track.”
The planet Neptune was actually predicted to exist before it was discovered, with the help of mathematics.
“It’s a situation that is similar to that of these small objects at the outer edges of our solar system in what we call the Kuiper Belt is very, very odd jobs,” Professor Duffy said.
“They all seem to be on the same side, preferably stacked, and the way to do this is to declare that it is the idea that the Planet is Nine, it is, in essence, he threw it with the force of gravity.”
He estimated that the Planet is Nine and is about 400 times further from the sun than we are, so finding the right type of like shining a flashlight into the west of Sydney, as well as the hope for east Perth with the.
It would have to be about 100 million times fainter than the faintest star we can see with our eyes, and guessed he was.
“The problem is that there is a huge amount of storage space available. Even a very large planet, much larger than the earth, it is a very, very small at that distance,” Professor Duffy said.
“If you’re looking for something very, very silly. The creature looks to be a very weak star, in principle, there are many of them out there.”
And it’s so far away that it probably takes about 10,000 years to make one complete orbit of the sun, which means that it moves very, very slowly.
“It is one of the smallest of the small gestures,” he said. “You’re effectively looking at half of the night sky and look to see if anything is weak, it is on the move.”
Professor Duffy is the equivalent to trying to find a needle that seems to be a lot of straw in a huge haystack.
“The solar energy system is deceptively large. Most of the people think that the planets are relatively close to each other, and with our telescopes, and have detected all of them.
“Nothing could be further from the truth. The actual space is huge. Even in the vicinity of the earth, and the space is filled with huge blocks of rock that have not yet been able to catalog yet, or even have to track it down.
“The further away you get from the sun, the more difficult it will be.”
To reduce the size of the solar system, in perspective, of a Professor She makes use of Australian locations and points of interest in order to have a point to make.
“When the Sun was at the Sydney Opera House, it would be the Earth’s orbit, the closer to the airport, as this is a Planet of Nine, it would orbit as far away as Perth,” he said.
However, the outer edges of our solar system, where there is a graveyard of huge chunks of ice to float and that is our long-period comets would be past the moon on this scale.”
Why does anyone care about getting a large chunk of the floating mass, which is really far away and uninhabitable?
Professor Duffy said the Planet is to Nine be able to discover what astronomers know about how planets are formed, in particular, in this part of the solar system.
“Something that is so far away, it will be a fascinating one. It will be a cold-hearted world. It will be like rocky? It will now be possible for a gas giant? I think it’s more likely to be something like a super-sized version of Pluto, but, then again, we don’t know. This is the reason why we have to try to get a better understanding of our own solar system, and how these “worlds” are constituted.”
