Like other members of the Kuiper belt, Pluto is composed primarily of rock and ice and is relatively small: approximately a fifth the mass of the Earth's Moon and a third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4–7.4 billion km) from the Sun. This causes Pluto periodically to come closer to the Sun than Neptune.

Pluto and its largest moon

first people in space

April 12, 1961 Vostok 1 a spacecraft with Yuri Gagarin was the first person to go into outer space, this man was a rusian astronaut who was on a pioneering trip as he did not know if he would come back and if the lauch would be successful.

Going to the moon

September 12, 1959 - Luna 2 is launched, impacting on the moon on September 13 carrying a copy of the Soviet coat of arms, and becoming the first man-made object to hit the moon.
December 4, 1965 - Gemini 7 is launched carrying Frank Borman and James A. Lovell, Jr., making 206 orbits around Earth and proving a trip to the Moon possible.
February 3, 1966 - Soviet Luna 9 is the first spacecraft to soft-land on the moon.
June 2, 1966 - Surveyor 1 is the first U.S. spacecraft to soft-land on the Moon.
July 20, 1969 - Neil Armstrong and Edwin Aldrin, Jr. make the first manned soft landing on the Moon, and the first moonwalk, using Apollo 11.

Saturn

Saturn means:
In astronomy mythology, Saturn was the god of agriculture, he was called Cronus by the Greeks. He is the son of Uranus, and father of Jupiter. Saturn over threw his father to become king of the gods, but was then over thrown himself by his son Jupiter.
How much would you weigh on Saturn?
Because Saturn is bigger than the Earth, you would weigh more on Saturn than you do here. If you weigh 70 pounds on Earth you would weigh 82 pounds on Saturn.

The Planet:
Saturn is a favorite object for many observers. Its beautiful rings are 169,800 miles wide, but less thick than a football field. In many ways Saturn is similar to Jupiter, but it is much smaller. Under the clouds of methane and helium the sky gradually turns into liquid until it becomes a giant ocean of liquid chemicals.

saturn has 34 moons orbiting around it. That is 33 more moons than earth as earth has only one moon.

As you mite not knone, our Sun is just a star. It’s our closest, most familiar star, but it’s still just a star. With a great big Universe out there, populated with countless stars, astronomers have been able to see examples of stars in all shapes, sizes, metal content and ages.

In general relativity, a black hole is a region of space in which the gravitational field is so powerful that nothing, including light, can escape its pull. The black hole has a one-way surface, called an event horizon, into which objects can fall, but out of which nothing can come. It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect blackbody in thermodynamics. Quantum analysis of black holes shows them to possess a temperature and radiate like black bodies.

The Sun (Latin: Sol), a yellow dwarf, is the star at the center of the Solar System. The Earth and other matter (including other planets, asteroids, meteoroids, comets, and dust) orbit the Sun,[9] which by itself accounts for about 98.6% of the Solar System's mass. The mean distance of the Sun from the Earth is approximately 149,600,000 kilometers, or 92,960,000 miles, and its light travels this distance in 8 minutes and 19 seconds. Energy from the Sun, in the form of sunlight, supports almost all life on Earth via photosynthesis,[10] and drives the Earth's climate and weather.

Pluto (pronounced /ˈpluːtoʊ/ (help·info),[8] from Latin: Plūto), formal designation (134340) Pluto, is the second-largest known dwarf planet in the Solar System (after Eris) and the tenth-largest body observed directly orbiting the Sun. Originally classified as a planet, Pluto is now considered the largest member of a distinct population called the Kuiper belt.[9]

you wondering how many planets are in the Solar System? Until just a few years ago, there were 9 planets in the Solar System. However, the International Astronomical Union decided that Pluto is no longer a planet, so there are now only 8 planets in the Solar system. Why is Pluto not a planet? We have a whole article that discusses this in great detail, but it happened because astronomers discovered a new object larger than Pluto out beyond its orbit. This object is called Eris, and it’s at least a few hundred kilometers bigger than Pluto. The IAU wondered if this object should be considered a planet too?

mars

Mars (pronounced marz/) is the fourth planet from the Sun in the Solar System. The planet is named after Mars, the Roman god of war. It is also referred to as the "Red Planet" because of its reddish appearance, due to iron oxide prevalent on its surface.Mars is larger and more massive than Mercury, Mercury has a higher density.

Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Ear It is the site of Olympus Mons, the highest known mountain in the Solar System, and Furthermore, in June 2008 three articles published in Nature presented evidence of an enormous impact crater in Mars' northern hemisphere, 10,600 km long by 8,500 km wide, or roughly four times larger than the largest impact crater yet dis Mars is the most likely to harbor liquid water, and perhaps life.[8] Radar data from Mars Express and the Mars Reconnaissance Orbiter have revealed the presence of large quantities of water ice both at the poles (July 2005)[9] and at mid-latitudes (November 2008).[10] The Phoenix Mars Lander directly sampled water ice in shallow martian soil on July 31, 2008.[11]
covered, of Valles Marineris, the largest canyon. With the exception of Earth, this is more than any planet in the Solar System.Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. Mars is larger and more massive than Mercury, Mercury has a higher density.

Saturn

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn, along with Jupiter, Uranus and Neptune, is classified as a gas giant. Together, these four planets are sometimes referred to as the Jovian, meaning "Jupiter-like", planets.

Saturn is named after the Roman god Saturnus (that became the namesake of Saturday), equated to the Greek Kronos (the Titan father of Zeus) the Babylonian Ninurta and to the Hindu Shani. Saturn's symbol represents the god's sickle.

The boundaries between the Earth's surface and outer space, at the Kármán line, 100 km (62 mi) & exosphere at 690 km (430 mi).Outer space (often called space) comprises the relatively empty regions of the universe outside the atmospheres of celestial bodies. Outer space is used to distinguish it from airspace and terrestrial locations. Utilizing a new instrument developed by scientists at the University of C
calgary, scientists have found that space begins 73 miles (118km) above Earth.[1]

From Wikipedia

It is often said that the Sun is an "ordinary" star. That's true in the sense that there are many others similar to it. But there are many more smaller stars than larger ones; the Sun is in the top 10% by mass. The median size of stars in our galaxy is probably less than half the mass of the Sun.
