write a short note on all the planets
Answers
Mercury is a planet in our solar system. It is the smallest of the eight planets. It is also the closest to the sun. Mercury goes around the sun the fastest of all the planets. Mercury has no moons.
VENUS:- Venus is the second planet from the Sun, and is Earth's closest neighbor in the solar system. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky.
EARTH:- Earth is our home planet. Scientists believe Earth and its moon formed around the same time as the rest of the solar system. They think that was about 4.5 billion years ago. Earth is the fifth-largest planet in the solar system. Its diameter is about 8,000 miles. And Earth is the third-closest planet to the sun. Its average distance from the sun is about 93 million miles.
MARS:- It is the fourth planet from the sun. It is the next planet beyond Earth. Mars is more than 142 million miles from the sun. The planet is about one-sixth the size of Earth. Mars is known as the Red Planet. It gets its red color from the iron in its soil. Mars has two small moons. Their names are Phobos and Deimos.
JUPITER :- Jupiter is the largest planet in the solar system. It is approximately 143,000 kilometers (about 89,000 miles) wide at its equator. Jupiter is so large that all of the other planets in the solar system could fit inside it. More than 1,000 Earths would fit inside Jupiter.

Answer:
Mercury
Mercury is the first of the four terrestrial planets. This means it is a planet made mostly of rock. The planets closest to the Sun—Venus, Earth, and Mars—are the other three.
Mercury is the smallest of the terrestrial planets. It has an iron core that accounts for about 3/4 of its diameter. Most of the rest of the planet is made up of a rock Crust.
Venus
Of all the planets, Venus is the one most similar to Earth. In fact, Venus is often called Earth's “sister” planet. As similar as it is in some ways, however, it is also very different in others.
Earth and Venus are similar in size. The two planets are very close to each other as they orbit the Sun; because of this, Venus is the most visible planet in the night sky.
Earth
The Earth is the only planet known where life exists. Almost 1.5 million species of animals and plants have been discovered so far, and many more have yet to be found. While other planets may have small amounts of ice or steam, the Earth is 2/3 water. Earth has perfect conditions for a breathable atmosphere.
Earth is the largest of the terrestrial planets and the fifth largest in the solar system.
Mars
No planet has sparked the imaginations of humans as much as Mars. It may be the reddish color of Mars, or the fact that it can often be easily seen in the night sky, that has caused people to wonder about this close neighbor of ours. Tales of “Martians” invading Earth have been around for well over fifty years. But is it likely that any kind of life really does exist on Mars?
Scientists aren't sure. Life as we know it couldn't survive there. Even so, there is evidence that there may be water on Mars. The presence of methane, which may be given off by organisms, provides another clue.
Jupiter
The planet Jupiter is the first of the gas giant planets. Made mostly of gas, they include Jupiter, Saturn, Uranus, and Neptune.
Jupiter is first among the planets in terms of size and mass. Its diameter is 11 times bigger than Earth, and its mass is 2.5 times greater than all the other planets combined. The “Great Red Spot” on Jupiter is actually a raging storm.
Saturn
Most people know about the rings around Saturn, because they are the brightest and most colorful. These rings are made mainly out of ice particles orbiting the planet. While the rings themselves seem big, the particles are very small, usually no more than 10 feet (3 meters) wide.
Saturn is the second largest planet. It is the farthest planet from the Earth that can be seen without a telescope. It appears flat at the poles because its great rotational speed makes the middle of the planet bulge.
Uranus
Uranus is the first planet so far away from the Earth that it can only be seen with the use of a telescope. When it was first discovered in 1781, scientists didn't know what they had found. As astronomers studied the object more closely, they discovered that it had a circular orbit around the Sun. They had found the seventh planet.
Uranus is so far from the Sun that it takes 84 years to complete an orbit of the Sun. It is the only planet that spins on its side, so each pole is tilted away from the Sun for half its orbit. That means each night and day lasts an amazing 42 years. Imagine staying awake that long! Of course, you'd also get a lot of time to catch up on your sleep!
Neptune
Imagine being so good at math that you could figure out the location of a planet you had never even seen! That is what John C. Adams did in 1843 when he discovered Neptune.
Neptune was named after the Roman god of the sea because it is so far out in the deep “sea” of space. The name also fits because Neptune appears to be a beautiful bright blue because of the methane clouds that surround it.
