Similarly, the planet Neptune is the eighth planet from the Sun and is primarily composed of gases, including water vapor, which is fitting given its namesake’s association with the sea.
10. How many planets are there in our solar system?
In our solar system, there are eight planets. These planets are Neptune, Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Uranus. Each planet is different from the others. Some are rocky like Earth, while others are giant balls of gas like Jupiter and Saturn. These planets orbit, or go around, the Sun, which is the center of our solar system.
11. What is the name for a planet outside the solar system?
C. Extraterrestrial planet
A planet outside of our solar system is commonly referred to as an “exoplanet.” These planets orbit stars other than our Sun, and they can be found in various parts of our galaxy and beyond. Scientists use various methods, such as observing the dimming of a star’s light as a planet passes in front of it or measuring the wobble of a star caused by the gravitational pull of orbiting planets, to detect and study exoplanets.
12. What is the name of the Sun’s visible surface?
The visible surface of the Sun is called the “photosphere.” This is the layer of the Sun’s atmosphere from which light is emitted and where most of the Sun’s energy is released as sunlight. When we observe the Sun, we see the photosphere, which appears as a bright, glowing disk. The photosphere, which is the lowest part of the Sun’s atmosphere, is around 5,500 degrees Celsius (9,932 degrees Fahrenheit)
13. In which year was Uranus discovered?
Uranus was discovered on March 13, 1781, by the British astronomer Sir William Herschel. This discovery marked a significant milestone in astronomy, as Uranus was the first planet to be discovered using a telescope rather than by naked eye observation. Herschel initially thought he had found a comet but later realized that it was a new planet orbiting the Sun.
14. What is the name of the largest moon of Pluto?
The largest moon of Pluto is named “Charon.” Charon was discovered in 1978 by American astronomer James Christy and his colleague Robert Harrington. It is about half the size of Pluto and is so large in comparison to its parent body that some scientists consider Pluto and Charon to be a “double planet” system. Charon’s discovery provided valuable insights into the Pluto-Charon system and enhanced our understanding of the dwarf planet and its satellite.
15. How many days does it take the moon to orbit the Earth?
It takes approximately 27.3 days for the Moon to orbit around the Earth once. This period is known as the “sidereal month.” However, when we observe the Moon from Earth, it appears to go through its complete cycle of phases (from new moon to full moon and back to new moon) in about 29.5 days. This longer period is known as the “synodic month” or “lunar month,” which is the time it takes for the Moon to return to the same position relative to the Sun as observed from Earth.
16. What is the name for a small body orbiting the sun, made of rock or metal?
Asteroids are rocky objects that range in size from small boulders to larger bodies several hundred kilometers in diameter. They primarily orbit the Sun within the asteroid belt, a region located between the orbits of Mars and Jupiter. Some asteroids also exist outside the asteroid belt, and they can occasionally come close to Earth’s orbit.
17. Which planet has moons called Phobos and Deimos?
The planet that has moons called Phobos and Deimos is Mars. These two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos and Deimos are relatively small and irregularly shaped moons compared to those of other planets in the solar system. They orbit relatively close to Mars and are thought to be captured asteroids due to their irregular shapes and compositions.
18. Which moon in our solar system is the largest?
The largest moon in our solar system is Ganymede, which orbits the planet Jupiter. Ganymede is even larger than the planet Mercury, making it not only the largest moon but also larger than some planets. It was discovered by Galileo Galilei in 1610 and has a diameter of about 5,268 kilometers (3,273 miles). Ganymede is composed mainly of rock and water ice and has its own magnetic field.
19. In which year was Pluto reclassified as a dwarf planet?
In 2006, Pluto was classed as a dwarf planet. This decision was made by the International Astronomical Union (IAU) during its General Assembly in Prague, Czech Republic, on August 24, 2006. As a result of this reclassification, Pluto is no longer considered one of the eight classical planets in our solar system but is recognized as a dwarf planet instead.
20. What is the Sun’s approximate rotation period at its equator?
The Sun’s approximate rotation period at its equator is about 24.47 days. However, it’s important to note that the Sun does not rotate uniformly across its entire surface. This means that different parts of the Sun rotate at slightly different speeds, with regions closer to the poles taking longer to complete a rotation than regions near the equator.
21. How many terrestrial planets do we have in our solar system?
We have four terrestrial planets in our solar system. These planets are Mars, Earth, Venus, and Mercury. Terrestrial planets are characterized by their solid, rocky surfaces and relatively thin atmospheres compared to the gas giants. They are located closer to the Sun compared to the outer gas giant planets.
22. Which spacecraft was the first to reach the vicinity of Jupiter?
The first spacecraft to reach the vicinity of Jupiter was NASA’s Pioneer 10. Pioneer 10 was launched on March 2, 1972, and it flew past Jupiter on December 3, 1973, becoming the first spacecraft to make a successful encounter with the giant planet. Pioneer 10 provided valuable data about Jupiter’s environment, magnetic field, and radiation belts during its flyby.
23. It takes how many minutes for light from the Sun to reach Earth?
It takes eight minutes and twenty seconds for light from the Sun to reach Earth. This duration is known as the “light travel time” and represents the time it takes for light, traveling at a speed of about 299,792 kilometers per second (or about 186,282 miles per second) in a vacuum, to cover the vast distance between the Sun and Earth.
24. What is the largest asteroid in the asteroid belt?
The largest asteroid in the asteroid belt is Ceres. Ceres is also classified as a dwarf planet due to its size and spherical shape. It is located in the asteroid belt between the orbits of Mars and Jupiter and is approximately 940 kilometers (about 584 miles) in diameter. Ceres comprises about one-third of the total mass of the asteroid belt and was the first dwarf planet to be visited by a spacecraft, NASA’s Dawn mission, which arrived at Ceres in 2015.
25. What is the name of the spacecraft that first landed humans on the Moon?
The spacecraft that first landed humans on the Moon is called Apollo 11. It was launched by NASA (the United States’ space agency) on July 16, 1969, and it successfully carried astronauts Neil Armstrong, Edwin “Buzz” Aldrin, and Michael Collins to the Moon. On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first humans to set foot on the lunar surface while Michael Collins orbited the Moon in the command module.
