THE SUN
The sun is our star, and it shanes a lot, that's what makes it a star, because the stars are shine.
The sun has a temperature of five thousand five hundred grades, even inside of it, the temperature's warmer than on the surface. Our star makes the live posible because its heat and its shine are essential for living. The sun is approximately the ninety eight porcentage of all solar system because it's really big. In fact, it could be all planets of our solar system inside the sun, even with extra space. The sun's really small to compared to others stars. In this moment, the star biggest of all universe is Uy scuti, it's approximately one hundred fifty thousand millions times bigger than the sun, but even so, it's colder than our star.
MERCURY
Mercury is the first planet in our solar system and it's the planet closer to the sun, approximately to fifty eight millon of kilometers from the sun. But even so, it isn't the planet warmest, mercury is around -180 grades at night but during the day it's 430 grades, it,s awesome because it,s cold but warm too, this is happen because mercury losed almost all its atmosphere and the sun storms make that mercury continues losing the little atmosphere that it achaives get. Now mercury is the smallest planet in all solar system. It has a lot of crater and these ones were photographed by messenger spacecraft and they're gray like the surface planet. The first planet doesn't have moons like venus, they're the only planets without moons.
VENUS
Venus is the second planet from the sun, it´s approximately to one hundred eight million of kilometers from the sun, this planet like mercury doesn´t have moons. It's the hottest planet in our solar system, its temperature is four hundred sixty grades, it's so hot that even the lead metls. Even worse, it is its atmosphere because it has a pressure that it's ninety times more heavy than the earth, that's why no spacecraft can't stay on the venus' surface for along time because of the tempeture and because of the pressure. Although of the conditions that venus has, some astronomers say that it could be microscopic live under venus' surface, because these organisms can live in extreme conditions. In the past, venus had live like in the earth, but unfortunately it had a change, where the planet started to increase its temperature and its pressure, transforming it, to what it's today.
EARTH
The earth is the only planet that it has live, nobody have found live in other planet diferent to the earth, though the astronomers have been finding live in other places, so far no one has found live out of our earth, there are similar planets like the earth and the experts think that maybe there's live in these planets, but this hasn't been proven yet. Our earth is the third planet from the sun, this distance is considerate one astronomical unit and this distance is essential for life in the earth. but, why does the earth have life?, they're a lot of thing that make possible the life in the earth, the third planet in our solar system has a good pressure, it has a adequate temperature, it's in the habitable zone and it has a atmosphere and this atmosphere has nitrogen approximately a sevent eight porcent, oxygen in a twenty porcent, and the rest gases are only the one porcent. The earth is the biggest rocky planet and it's the densest among the eight planets in our solar system.
Our planet has one moon and it helps to the earth to control the waves so that the water stay in the ocean
MARS
Mars is the fourth planet in our solar system and the people know it as the red planet, the atmosphere of mars gives the color to the planet. The astronemers have sent spacecrafts to this planet, in fact, this planet is one of the planets more investigared in our solar system. Mars has a temperature of sixty grades below zero, it's so cold. Mars has a pressure lower than the earth, its temperature, its atmosphere and its pressure make imposable the life in this planet. Mars has two moons their names are fobos and deimos, and they're smaller than the earth's moon. Mars has the largest mountain in all solar system, its name is olympus mons, it's three times more larger than the everest mount.
