THE SOLAR SYSTEM : How horrible the space is or is it amazing and beautiful

1. Sun

 The sun is the energy source that provides light, heat, and life to our planet. Without the sun, we would not have any plants, animals, or humans. The sun also gives us a lot of energy in the form of sunlight. This energy allows the use of different types of plants. It can be used by using solar panels.

1. Mercury - Smallest planet, hottest surface temp

 Mercury has no magnetic field, and its atmosphere is extremely thin. Mercury's gravitational force makes it difficult for spacecraft to land, but it does have a dense iron core. Mercury is the closest planet to the sun, making its days are shortest at only 58 Earth years. Mercury's day lasts 88 earth hours. On average, Mercury rotates once every 59 days.

 2. Venus - Second smallest planet

 Venus is covered in thick clouds that cover about 60 percent of the planet, leaving the remaining 40 percent clear. Venus' high pressure atmosphere prevents water from escaping into space, meaning the planet may be composed entirely of liquid. Venus has a thick carbon dioxide atmosphere, which keeps temperatures hot enough to melt lead. Because of this, Venus' days last 243 earth days due to its slow rotation, which takes 225 earth days.

 3. Earth - Largest Planet & Home

 Earth is the largest planet and our home. The gravity of Earth creates a strong pull towards the center of the planet. Its orbit around the sun causes the seasons. The tilt of the axis causes differences between the northern and southern hemispheres. This tilt allows us to experience various climates. Earth is the third rock from the Sun, the other 2 being Mars and Jupiter. Due to its proximity to the Sun, Earth is the only known planet to have life.

 

 4. Mars

 Mars is the second closest planet from the sun. It has many rocks and deserts that are covered in sand. It also has volcanoes that breathe out gasses that help make the air breathable. There are no people on mars but if there were people they could survive there because the air is breathable.

5.JUPITER

Jupiter is the fourth largest planet in our solar system. Jupiter is massive, consisting mainly of gas but has over 300 moons orbiting around it. Jupiter's mass is about 318 times that of Earth and its radius is almost 12 times greater than that of earth. It takes Jupiter 8 years to orbit the sun.

 The first moon discovered was Io, which orbits Jupiter twice each day. There are many other moons that have been discovered, but not all their movements are known yet. The most famous moons are Ganymede, Callisto, Europa, and Io.

 Ganymede is Jupiter's largest moon and contains huge amounts of water ice. In fact, much of Jupiter's atmosphere consists of hydrogen and helium. This means that Jupiter may have a core of liquid rock.

 Callisto is a dull-colored moon with little activity. It appears similar to Ganymede. Some astronomers believe that Callisto holds vast quantities of water ice just like Ganymede. But it is unknown whether Callisto ever had a magnetic field.

 Europa is probably the best studied body in our solar system. Europa's surface temperature averages -180C (-292F). Scientists say that Europa is covered in a thick layer of ice. They think that if something melts this ice from beneath, then Europa might possibly hold a large amount of liquid water. A large ocean lies below Europa's crust. If this would happen, Europa could provide a home for life and could be a good place to look to find extraterrestrial life.

 Io is Jupiter's smallest and least dense moon. Its diameter is only 5,000 km (3200 mi) and it weighs less than 1/10th of that of our moon. However, Io gets much closer to Jupiter than any other moon. It orbits at about 2 million km per hour. As it gets closer, it speeds up faster and faster until it approaches Jupiter's gravity. When it makes contact, it breaks away from Jupiter and begins to orbit the sun. But eventually, it re-approaches Jupiter again.

6.SATURN

Saturns gravity is 9 times stronger than earth's gravity and is about 60 million miles away from our sun. Saturn has rings that are almost two thirds of the diameter of the Earth. Saturn has some of the largest moons in our solar system including Titan, Rhea, Dione, Enceladus and many others! Some of these moons have lakes of liquid methane!

Saturn is the sixth planet from the Sun and the second largest planet in our Solar System after Jupiter. This giant gas planet has been known since antiquity. Its discovery by William Herschel in 1789 marks its official entry into modern astronomy. In ancient times, Saturn was considered the king of planets and was believed to have many features similar to those attributed to the Earth’s moon.

7.URANUS

Planet Uranus is known to be cold, dark, and mysterious. This planet has been known to hold many secrets that have yet to be discovered. One secret was recently revealed...

 Uranus is known to be the first planet where life took form on Earth. Scientists are still unsure about what kind of life exists there. What they do know is that some of the conditions on this planet may be similar to those on Earth now. A team of scientists led by Dr. Thomas M. Pappalardo from NASA's Goddard Space Flight Center in Greenbelt, MD believe that planets like Uranus could house the building blocks of life.

 The research team studied Saturn's moon Enceladus. They have determined that Enceladus contains water ice underneath its surface. If water can exist on Enceladus, then perhaps other worlds in our solar system could have the potential to host life.

 Scientists believe that there are several possibilities of how life formed on Uranus. Some think that it developed through geological processes while others believe that organic compounds existed on the planet long before life ever came into existence. Other theories suggest that life arrived on Uranus via meteorites.

 8.NEPTUNE

 Neptune is a gas giant that orbits the Sun at roughly 30 AU (30 times further than Earth). This distance provides us with some great opportunities for observing this planet, but it comes with its own challenges. Neptune’s high elliptical orbit means that it spends much less time near the Sun than Jupiter does. When we look at Neptune from Earth, it appears to move along the sky rather slowly compared to other planets. Because of this, it has been challenging to get close-up images of Neptune and scientists have had to rely on indirect methods to study this planet. Luckily, Neptune makes several passes in front of our star each year and can be observed for brief moments. In fact, Neptune is the closest non-Jovian planet to the Sun. 

8.PLUTO

Pluto, (also known as Krypton) was the 7th planet from the Sun. Pluto is named after the Roman god of the underworld. Pluto's moon Charon is named after Charon, the ferryman who carried souls across the river Styx. Pluto has three moons that are relatively large compared to their parent planet; Charon, Nix and Hydra. Pluto rotates about its own axis once per year. Pluto's surface temperature averages -290 degrees Fahrenheit!.
