AI, BASIC AND SIMPLE INFORMATION ABOUT THE PLANETS
The Sun, the Moon and the planets are essential components of the solar system and have been objects of study and admiration throughout history.
The Sun is a star located at the center of the solar system and is the primary source of energy for the Earth. Its main composition is hydrogen (approximately 75%) and helium (about 24%), with other elements in smaller proportions. Through a process called nuclear fusion, the Sun converts hydrogen into helium, releasing energy in the form of light and heat. It has a diameter of approximately 1.39 million kilometers, and its mass is 330,000 times that of the Earth.
The Moon is the only natural satellite of the Earth and is the fifth largest satellite in the solar system. It has a diameter of 3,474 kilometers and is located at an average distance of 384,400 kilometers from the Earth. It
has no light of its own; It reflects light from the Sun. Its phases (new, crescent, full and waning) depend on its relative position with respect to the Earth and the Sun. It has been the subject of space missions, the most famous being the Apollo 11 moon landing in 1969.
The Kuiper Belt and the Oort Cloud are two regions of space that contain numerous celestial bodies, mainly icy objects, and that are located at the limits of the Solar System.
Kuiper Belt :
It is a region of space that is located beyond the orbit of Neptune, approximately 30 to 55 astronomical units (AU) from the Sun.
The planets : There are eight planets in the solar system, divided into two groups: the rocky planets (Mercury, Venus, Earth and Mars) and the gas planets (Jupiter, Saturn, Uranus and Neptune).
Mercury : The closest planet to the Sun, it is the smallest and has a very thin atmosphere; it is the closest planet to the Sun; with a diameter of about 4,880 kilometers, with a very thin atmosphere composed of oxygen, sodium, hydrogen, helium and potassium; with temperatures that can vary drastically, from -180 ° C at night to 430 ° C during the day and a surface full of craters, similar to the Moon, and it has no moons. It has been explored by missions such as Mariner 10 and MESSENGER. Venus
: Similar in size to Earth, but with an extremely dense and hot atmosphere.
Earth : The only known planet that supports life, with an atmosphere rich in oxygen and water in a liquid state.
Mars - Known as the "Red Planet," Mars is the fourth planet in the solar system, located between Earth and Jupiter. Its distinctive color comes from the iron oxide on its surface. Mars is about half the size of Earth, with a diameter of about 6,779 kilometers.
Fast Facts About Mars:
Atmosphere - Mars has a thin atmosphere composed mostly of carbon dioxide, with traces of nitrogen and argon. The atmosphere is much less dense than Earth's, which means the weather is more extreme and temperatures vary dramatically between day and night.
Temperature - Mars can range from about -125 degrees Celsius on winter nights to 20 degrees Celsius in the day near the equator.
Surface - Mars has varied geography including mountains, valleys, craters, and volcanoes. Olympus Mons, the tallest volcano in the solar system, is located on Mars and is about 22 kilometers high.
Moons - Mars has two small, irregularly shaped moons, Phobos and Deimos. These moons are much smaller than our own and have orbits very close to the planet.
Water - Although there is no liquid water on the surface of Mars, evidence of frozen water at the poles and possibly liquid water below the surface has now been found.
Mars is a prime target for space exploration due to its relative proximity and similarities to Earth, making it a potential candidate for future human colonization. It has been the subject of numerous exploration missions, both with orbiters and with rovers on its surface. NASA, among other space agencies, has sent several successful missions, such as the rovers Spirit, Opportunity, Curiosity and Perseverance.
Jupiter: the largest planet in the solar system, composed mainly of hydrogen and helium, with a famous ring system and numerous moons.
Uranus : Position : Seventh planet from the Sun; diameter about 50,724 kilometers with an atmosphere composed of hydrogen, helium, and methane, giving it its blue-green color; it is one of the coldest planets, with temperatures around -224 °C. It is an ice giant, with an interior composed of frozen water, ammonia, and methane. It has 27 known moons. It was briefly visited by the Voyager 2 probe in 1986.; An icy planet, with an extreme tilt of its axis, causing unusual seasons.
Neptune : Eighth planet from the Sun with diameter about 49,244 kilometers; Atmosphere: Composed of hydrogen, helium, and methane, similar to Uranus, giving it a deep blue color; Temperature : About -214 °C. Surface: Another ice giant, with strong winds and storms. It has 14 known moons, the largest being Triton; It was also visited by Voyager 2 in 1989; the most distant planet from the Sun, known for its strong winds and deep blue color.
These celestial bodies are not only part of our solar system, but have also been fundamental in the understanding of astronomy and cosmology.
Venus: second planet from the Sun and similar to Earth, with a diameter of about 12,104 kilometers: very dense atmosphere composed mainly of carbon dioxide, with clouds of sulfuric acid; it is the hottest planet, with temperatures up to 470 °C due to an uncontrolled greenhouse effect; surface : rocky, with volcanoes and plains, but not visible from the outside due to the dense atmosphere; it has no moons; missions such as Venera (from the Soviet Union) and Magellan (from NASA) have explored Venus.
Saturn: Known for its spectacular ring system, it is also a gas giant; sixth planet from the Sun: diameter of about 116,460 kilometers, it is the second largest planet with an atmosphere composed mainly of hydrogen and helium and a temperature around -178 °C. It is a gas giant without a solid surface and is famous for its rings. It has more than 80 moons, the largest being Titan. The Cassini probe studied Saturn and its moons for more than 13 years.
Pluto (dwarf planet): previously considered the ninth planet, it is now a dwarf planet in the Kuiper Belt with a diameter of about 2,377 kilometers, atmosphere : very tenuous, composed mainly of nitrogen with traces of methane and carbon monoxide, extremely cold temperature , around -229 °C with mountains and plains of nitrogen ice. It has five moons, the largest being Charon. It was explored by the New Horizons probe in 2015.
