Hogwarts and the Atypical Wizard

At 11 o'clock in the evening there was an astronomy class, and everyone gathered in the astronomy tower with their telescopes.

Professor Sinistra asked, "How many planets are there in our solar system? Can anyone tell me?"

Everyone could answer such a simple question. The students answered in varying degrees, "Nine planets!"

Sainz subconsciously wanted to refute, but then he held himself back.

Suddenly I realized that during this period of time, Pluto had not been expelled from the planet.

Today, there are still nine planets in the solar system, not eight.

There is an interesting story behind Pluto being expelled from the planet list, but Sainz didn't write it down in his notebook because he was in class.

In fact, this planet has only been discovered for a few years, it seems to have been discovered in the 1930s.

I don’t know whether a wizard contributed to the discovery of this planet, and I don’t know whether there are wizards in the International Astronomical Union.

"Well, last school year we studied several large planets, and this school year we are going to observe these relatively small planets that are closer!

So after hearing these hints, does anyone know which planet we are going to observe today?

I think it's a good judgement, isn't it! "

Compared with large planets such as Jupiter and Saturn, the planets within Jupiter's orbit are relatively small. The smallest of them is Mercury, which is also the closest to the sun.

Someone said without hesitation, "Mercury!" The other students nodded in agreement.

Sainz has a different opinion. "Although I know this may make me seem a little ignorant, I have a different opinion. I think it is Mars, professor!"

"Oh, tell me your reasons!"

“Professor, you said it was a relatively small planet that was relatively close, and the range was limited to the orbit of Jupiter.

There are four planets within the orbit of Jupiter, apart from the Earth beneath our feet, the remaining are Mercury, Venus, and Mars.

However, because the orbits of Mercury and Venus are within the orbit of the Earth and because of the angle between their orbits, they can only be seen in the sky at dawn and dusk in the Northern Hemisphere.

It's midnight, so only Mars is left! Professor!"

“Great! That’s great!

Ten points for Hufflepuff!

Indeed! As Autumn said, Mercury and Venus only appear in the early morning or evening, and because Mercury's orbital period is very fast, our chance to directly observe it is not available every day.

Also, Mars is not visible every day.

This year happens to be the year of the "Mars opposition" that happens every two years. You are very lucky that you can see it in the second grade. Some unlucky students need to wait until the third or fourth grade to have the opportunity. "

"Professor, what is Mars opposition?" Cedric asked in confusion, which was also the confusion of other students.

"Oh, Mr. Diggory, and the rest of you, the opposition of Mars is when Mars is closest to the sun and the earth. At that time, you can even see this red planet with your naked eyes without a telescope."

"So will it be in opposition to the sun soon?" Cedric asked.

“Not yet, but I guess it will appear in mid-to-late November, and you will be able to feast your eyes then.

All right, now everybody, grab your telescopes, point them south, raise them forty degrees above the horizon, and find this fiery red fellow."

Everyone followed the professor's instructions and adjusted their telescopes. With the specific location information, the students helped each other and found it quickly.

"Does anyone know what it was called in ancient times?"

Drizzt Benton of Ravenclaw said, "In ancient times they called it 'Mars', Professor!"

"Yes, Mr. Benton is right. In ancient times, it was called 'Mars', the god who dominated war, land, agriculture and spring in Muggle mythology.

Sometimes I admire the imagination of Muggles and I can't understand how they connect all these things together.

However, we are wizards, we have to look at this problem objectively. We are studying astronomy, which is a subject with real meaning, not some meaningless myth that some people have wildly imagined.

You are wizards, and you may become leaders in various fields in the future. You must abandon those foolish ideas of idolatry. Astrology is astrology, and it has nothing to do with any unknown gods. "

As he spoke, Professor Sinistra began to get excited.

Sainz interrupted her and joked, "Professor, it seems that our Mr. Mars is a little sloppy today. He seems to have forgotten to wash up. He looks gray and dirty!"

"Ha ha……"

"That's right, Sainz is right, he really doesn't look rosy today..."

"Really? Let me see, why can't I see it?"

"I think your telescope is pointed at some other star next to it..."

After being interrupted by Sainz, Professor Sinistra regained his composure, "This is normal, kids, it's just an ordinary planet, it has an atmosphere, sometimes it raises sandstorms all over the sky, and every time this happens, it looks like this.

Let's just say you're lucky, you don't always see the sky full of dust, so you just happened to draw it."

The astronomy professor gave everyone paper and pencils, and everyone began to complete today's homework in silence.

The good thing about astronomy class is that there is never any homework. All star maps will be completed in class and it will not take up the little wizards' spare time at all.

At 11:45, Professor Sinistra announced the end of today's classes.

Now Filch no longer bothered to wait here, as all his attention was drawn to the Gryffindor twins.

Less than a week into the new semester, the twins were already forced to clean the toilet, and were not allowed to use magic.

I don't know if these two guys are addicted. Even though they are often punished, they still enjoy going against Filch.

On Saturday morning, Sainz rarely went to the eighth floor early in the morning.

Strolling around the Black Lake, playing with Speed ​​for a while.

"Boy, have you gained weight again?

I remember you used to weigh just over one kilogram, but now you weigh at least three kilograms!

Are you sick?"

Speed ​​jumped up impatiently and turned his head away.

He looks full of energy and doesn't look like he's sick.

"Come here, let me see if you've grown taller. Hey, it seems you've actually grown a little taller!

Are you still a baby? Still growing?

Hehe, if you could really grow to the size of a fire dragon, hehe... Hagrid would definitely cry with envy!

Hey! Hey?

What is that look in your eyes!

You are a bit offensive!"

Before he could say a few words, Speed ​​jumped up from his arms and flew away.

Sainz felt insulted by a big blue-gray bird!

After thinking it over, I was so angry that I went to the lake and fiddled with the giant squid's tentacles that had stretched to the shore several times...
