6 space errors
The space is extremely charming and highly mysterious thing. To know her completely is not enough for eternity. And maybe we don’t want to know then? We do not believe that that is necessary. And we should start with the common misconceptions about home Solar system in order, as they say, away from home not to go, because some of the facts we used to see a bit of a misnomer.
1. Little Earth
When most of us think about the Solar system, what is a put on an eternal orbit around the Sun guard on the planet. Burning like a demon from «Diablo», the star and colorful balls near planets.
Can you guess what’s wrong? And the fact that the size of our planet is greatly exaggerated on different star atlases.
If you portray real correlation, it is necessary to draw muddy blue pixel.
Now, when we found out that we, roughly speaking, the size of a hair follicle on a giant flaming testicle, which warms us all, let’s talk about the planetary orbits. We’ve learned that it’s the right circles, by which the balls revolve, the planets hanging close to each other. In fact, the fiction far from the truth. Elipsocidae orbit and spinning of the planet at different angles and at different distances from each other, so no one was uncomfortable.
2. What made the comet
We tend to assume that the comet is basically a giant galactic beauty with a beautiful tail, when he saw that to make a wish. But comets are basically large chunks of ice and other space stuff, and everything else that we see in them: the light, the tail – everything is a miracle given by the sun.
At a distance of about five astronomical units (one unit = 93 million miles, or the distance from the earth to the Sun), the Sun begins to warm the comet with sufficient force to sublimate some of the ice directly from a solid to a gas, and the gas is mixed with dust to form that magic halo around the comet called the coma. Tails (actually two) grow from this. One of them is a plasma tail of ionized gas, and the other is just from the dust.
A plasma tail is formed when the solar wind gets into a coma (that sounds weird, well, God bless him) and ionizes the gases. The dust tail is amenable to solar radiation pressure and steers away from the sun. You would too if I was a celestial body. The sun is a little hard.
We know our inquisitive friend that you were aware that the comet is not magic, but a cosmic matter, but… Well, we just had to write about them.
3. Pluto is not as simple as it seems
«Rick and Morty», «Futurama» – pop culture and the curriculum presented Pluto as icy, blue-gray piece of crap – the sort of space version of Antarctica. After all, he is far from us and the Sun, so there must be cold, and cold, as in Sweden, everything and everyone makes blue, right?
Maybe the authors of the textbooks and cartoons confuse the color, but Pluto is not grey or blue. Like all normal planet, it is brown-red. Pluto is the same color as Mars, but the reason this painting is so much cooler: Pluto got his «tan» due to space and sunlight, razvratnymi methane directly on the surface and in the atmosphere. In General, a lot of attention is paid to the unfortunate Pluto, and he’s even some time not considered a planet.
4. How many days where
The idea is that the shortest day should be like on mercury nearest to the Sun planet. But the longest – on loser Pluto. If it is to follow the laws of common sense, that don’t work, if it comes about space and especially about the Solar system.
Jupiter, the largest planet in the system, has day only 9.9 earth hours. If you lived there, you would day is not enough for viewing all parts of the Lord of the rings. Meanwhile, roughly earth-size Venus has a day of 243 earth days. By the way, its orbital period is pathetic 224,7 days. If we could make crazy onersquo the atmosphere, you would enjoy 116 hours of sun per day. The main thing is not to work all day.
The speed at which the planet rotates, is determined by the time of its creation, and it has nothing to do with its size or composition. When a star forms, it creates a disk around which lumps of matter, forming the planet.
The first prototypes of the planets spin the same speed as the disk, but as soon as they interact with other materials, their speed increases or decreases until, until they settle into a safe orbit. From this point the planets revolve at the speed which was after their last interaction.
Science is recovering after decades of hypotheses and the hangover, and begins to understand the intricacies of planetary rotation. Studies show that the speed of rotation of the planet has a huge impact on its potential habitability. Apparently, Jupiter is no one living because of overly rapid rotation all feel a little sick.
5. Not all satellites are the size of the moon
Traditionally, the Month may be a small piece Americans conquered space orbiting our planet. But when the scale, the worst enemy of anyone trying to comprehend the space comes into play, we notice that many satellites are suspiciously large. For example, Jupiter’s moon Ganymede or Saturn’s Titan. With their size they can easily secturity and courageous symbol of war Mars, and hot mercury.
And that there’s plenty of asteroids, with dimensions not inferior to one Month.
6. The solar system is more than it seems
Where is the border of the Solar system? It’s Pluto, Yes? Is 39.5 astronomical units – this is the extreme outer body from the Sun, so its orbit surely marks the walls of our cosmic cradle. But in fact, Pluto is even close to the edge is not.
To find out where the end of the Solar system, we first need to put another seemingly stoned question: what is the Sun?
«It is a star, stupid», – you say. True. But what is a star?
There is no need to roll your eyes, it really is a serious question. The star is in fact a compact series of gas explosions, so hot that due to the large supply of hydrogen is constantly undergoing nuclear reactions throughout the star. You could say it’s like the farting of a hydrogen bomb.
A giant ball of nuclear explosions, and his influence extends far beyond the flaming disk which we see in the sky. The solar wind is constantly blowing in all directions, spewing plasma and particles into space at supersonic speeds. He holds the interstellar medium, dust, gases of interstellar space – fear. The solar wind eventually weakens, slows almost to a subsonic velocity, and this limit is called the termination shock wave.
This is not the end of the Sun, the effective range is only the start of the next stage, called the heliosheath English. Here, the solar wind is moving at a slower speed, subsonic, compressed. Finally we reach the heliopause, where solar wind and interstellar matter, finally, mutually exclusive. This marks the outer rim of the sun to the heliosphere and, thus, in our Solar system. Now we at least 121 astronomical units from the sun, three times farther than Pluto, but 5 times less than your mother,» joked would stand-up.
The reason is simple: our Solar system is constantly moving. We are, in fact, a rocket screaming through space at a speed of 45,000 km/h, being pushed back interstellar shit and the solar wind.
So, our entire Solar system is a giant rabid muscle, gleefully tearing ass through space. And who said that astronomy is boring?
