It was her favorite bit, so she knew she was really going to enjoy this lesson. But...now she needed to think about the question. She mused, flicking through her textbook to the bit about planets, although she knew the answer probably wasn't going to be in there. You know, considering that the Professor had asked about a muggle thing. With a smile though, she raised her hand after a few minutes. "I think to qualify as a planet it has to orbit the sun" Professor Roslund beamed at Indiana "Yes that is correct. One requirement is that the planet has to orbit the sun. 1 point to Ravenclaw!" she was the last one in and the first to answer. Quote:

"Very good Alyssa, 3 points to Hufflepuff." Edvard said as he turned to the badger. Someone clearly knew their astronomy by heart. Quote:

"A planet is a celestrial object that has an orbit around the sun, has enough mass to hold a near-round shape and there is clear space around its orbit," he replied doing his best to put it in his own words. "Spot on Gideon, 3 points to Gryffindor!" Edvard said with a beam to the lion boy. It seemed that planets were something which interested many of his students. Quote:

"That's why Pluto was downgrated to dwarf planet because it shared its orbit with other dwarf planet." Yep, poor little Pluto. "Very good Kennedy, 1 point to Slytherin! Pluto was indeed downgrades to a dwarf planet because it shares and orbit eith another dwarf planet." Edvard replied with a smile. Quote:

Edvard said with a little wink in the first year's direction. Quote:

A planet is any object in orbit around the Sun whose shape is stable due to its own gravity.
A planet is any object in orbit around the Sun that is dominant in its immediate neighbourhood." Sorry Professor but I wasn't sure which one you ment.' She finished off. Blink? "Good Salima, 3 points to Hufflepuff! I will go into the requirements of a planet when everyone has had a chance to answer." Edvard said firing of a smile in the little girl’s direction. Quote:

1. It orbits the sun, 2.It has sufficent mass assuming a round shape and 3."Cleans it's neighborhood" around the orbit. William told the professor. "Very good William, 3 points to Gryffindor!" Edvard said with a smile to the young lion. Quote:

She rose her hand to respond to the question herself and said simply, because that was about the only answer she had, A body of mass that takes up space as it orbits around the sun?" That was all she had for him. Turning to another lion, this time a girl Edvard nodded "Yes, good Selina, 1 point to Gryffindor." Quote:

They'd been over it so many times in her muggle science classes it was ingrained. " A planet is a celestial body that obits a sun, has enough mass to be round, and has nothing in the way of it's orbit." she answered. "Excellent Sky, 3 points to Slytherin!" Edvard said with a beam to the little snake. Quote:

"Professor, a planet is categorized in three ways. It orbits the sun, has sufficient mass to form into a round shape, and it clears the neighborhood....which means it has become gravitationally dominant." "Excellent Kourtney, 3 points to Gryffindor!" Edvard said with a beam to the young lion. Quote:

She named the planets correctly too but he hadn't asked for them. Quote:
Originally Posted by sweetpinkpixie "Planets are celestial bodies which are gravitationally dominant with no other bodies close to it in comparable size besides it satellites. It also should have enough mass to create a spherical shape." There was some fancy word for that that started with hydro-- and ended with something, but Kurumi sort of let that slide for now because she knew she would only butcher the pronunciation. "They also must orbit around the sun, or, um, A sun." Since their galaxy wasn't the only solar system in the galaxy. The universe didn't revolve around them after all. "Excellent Kurumi, 3 points to Gryffindor!" Edvard said with a beam to the young prefect. Quote:
Originally Posted by anolan807 Minerva wasn't completely sure, but she put up her hand. "Professor does it mean something along the lines of the planets orbiting the sun." "Indeed it does Minvera, 1 point to Hufflepuff! A planet does orbit the sun." Edvard explained to the little badger. Quote:
Originally Posted by DracoLover2611 Rasing his hand Anthony said aloud, "Umm I heard when I was younger that a planet has to orbit the sun or something like that, and that it doesn't die out... or something?" He was taking a total guess mostly. He heard his Uncle talking about it once at a family gathering, but he was so young he doesn't really remember to much except that is much orbit the sun. "Good Anthony, 1 point to Hufflepuff! A planet orbits the sun." Edvard said reassuringly to the little badger. Why were they so uncertain when they were right? Quote:

"For a celestial body to be a planet, it must pass three tests. The first is that is must orbit a star, in our case the Sun. At least, I think it can orbit any star. Or are they only called planets in our Solar System? That would kinda leave out the other psuedo-planets.." He was digressing. Bring it back, Keef.
"Anyways, sorry. So it has to orbit a star or the Sun. The second test is that it has to have enough mass that it has become spherical. This is closely related to the third test, which is that the body must have become the Alpha Dog of its neighbors. Basically, its gravitational pull has to dominate the gravitational pull of any body 'close' to it."
Though really, how do you define close when distances are measured in millions of miles or light years? "Excellent Keefer, 3 points to Hufflepuff!" Edvard said to the little badger. This seemed to be a class where student's of all houses were raking full points on the questions. Quote:

"Very good Raven, 2 points to Slytherin!" Edvard said with a smile in the young girl's direction. Quote:

Well that's the simplified version. "Good Janice, 1 point to Hufflepuff." Edvard said encouragingly to the little badger. Quote:
Originally Posted by tomewitch After letting a few other students share their answers, Beezus raised her hand, "A planet is a celestial body that is in orbit around the sun. It also has sufficient mass to assume hydrostatic equilibrium or having an almost round shape and has cleared the neighborhood around its orbit Professor." She asserted. Being a half blood witch certainly have its advantages. And reading books once in a while was another addition. "Excellent Beatrice, 3 points to Ravenclaw!" Edvard said to the little badger. Quote:

"A planet is a ...something that has a difficult name... body that is something about a orbit around the sun." He said while still looking at the cloth. What? he was curious! Until he moved his eyes away from the cloth and looked at the Professor.
"I don't know more..." he sighed , his answer hadn't even been that good either but whatever. Atleast he triiied!~ "Good Daichi, 1 point to Slytherin! It's good that you tried." Edvard nodded at the boy encourangingly. If you don't try then you can't gain anything. Quote:
Originally Posted by KP1 Ryan let everyone say there answers before he put his hand up to say what he thought a planet is.He said ''A Planet is a Celestial Body that must orbit the Sun and can have Human Life on it Or not.''That was his answer,It might not have been the best but it was from his point of view. "Good Ryan, 1 point to Gryffindor!" Edvard responded to the little lion boy. Quote:

And he opened it. And Elise just stared for a moment. A solar system model! Squee!
The definition of a planet? Her mom had explained it to her when she was little. Tapping the side of her head, she tried to recall the vague memory....
Got it.
"The muggle IAU clearly stated in 2006 that to be classified as a planet, it must firstly be a non-satellite celestial body," she said with her hand raised, quoting her Astronomer mother word for word. "It must also be gravitationally dominant around its own orbit, also known as 'clearing the neighborhood'. A planet must also orbit around a star, or a sun, and have sufficient mass to maintain a hydro-static equilibrium."
Out of breath, she lowered her hand, inhaling deeply. The memory was one of her now-dead mother, and Elise tried hard to fight the tears that threatened to wash over her.
"Excellent Elise, 3 points to Ravenclaw!" Edvard responded.

Taking out his wand he directed it towards the blackboard. Quote:

As the text started to appear Edvard turned to address the class "First of IAU stands for the International Astronomical Union. They definied a planet quite a few years ago now. The requirements for a celestial body to be called a planet is that it orbits around the sun, has sufficient mass to be able to assume a nearly round shape and has a clearned its orbit of other celestial objects." "Looking back at the first lesson of the year, many of you mentioned that Pluto has now been classified as a dwarf planet. What is the difference between a dwarf planet and regular planet?"
