Mercury, Venus, Earth and Mars are called the terrestrial planets (Inner Planets).
Terrestrial planets are Earth-like planets (in Latin, terra means Earth) made up of rocks or metals with a hard surface — making them different from other planets that lack a solid surface. Terrestrial planets also have a molten heavy metal core, few moons, and topological features such as valleys, volcanoes and craters.
Mercury can produce a magnetic field 100 times weaker than the Earth. It takes Mercury 58.6 days to rotate and 88 to orbit the sun.
Venus is an oppressively hot world. Although not the closest planet to the Sun, Venus has the highest surface temperature of all the planets, averaging 464 celsius. The clouds trap the heat from the sun, creating a greenhouse effect.
The Earth takes 23.9 hours to fully rotate and 365.3 days to complete its orbital path around the Sun. It’s the only planet in our Solar system known to support life or water. The atmosphere has been greatly transformed by the existence of life throughout much of its history.
Ancient floodplain and network of dry riverbeds are clear evidence that large amounts of water flowed across the surface of Mars billions of years ago, when the planet was much warmer than it is today.
Jupiter completes one orbit in just 12 years. Like all other planets, it rotates as it travels, turning once in just less than 10 hours. Jupiter has a grand total of 60 moons!
Named after the one-time ruler of the Roman gods and father of Jupiter, Saturn is the sixth planet from the sun. It is nearly twice as far away as it’s larger inner neighbour, Jupiter, and it takes almost 29.5 years to complete one orbit around our star.
Uranus takes 84 years to complete orbit around the sun. On each orbit, the North and South poles experience 42 years of darkness and 42 years of continuous sunlight.
Neptune takes 164 years to orbit around the Sun once. Neptune is the furthest away planet in our solar system, and has 14 moons. Neptune’s largest moon is called Triton, and is named after the Greek god of the ocean (Neptune is the name for the Roman god of the ocean).
The sun is 4.6 billion years old and is expected to live for 10 billion which means that in 5.4 billion years the sun will explode.
Also known as minor planets, asteroids are small bodies made of rock and metal that follow independent orbits around the sun. The vast majority lie in a concentration called the main belt. The largest of these, Ceres, was only discovered in 1801 and was reclassified as a dwarf planet in 2006. The asteroid belt lies between Mars & Jupiter.
Get ready for some more mind blowing, spine chilling Unsolved Alien Mysteries!
In Italy, a mysterious feathery substance was seen falling from the sky in the 1950s, supposedly left behind by UFOs. This “angel hair” (as it was called) floated down for two hours after a UFO had been spotted. However, this puzzling element disappeared as soon as it touched the warm ground or human skin. After being examined by scientists, they discovered that it was a form of glass!
In 1961, a forester in Karelia, Russia came across a large, newly made crater on the bank of a lake. The forester called for scientists and divers to look at the strange hole. After being searched, it was thought that a gigantic UFO had skidded to a halt there. But there wasn’t a trace of a crash landed spaceship anywhere. Inside the crater was a mysterious green ice! To this day, no one knows exactly what made the crater, or where the green ice came from.
In 1966, two pieces of green and blue paper were found next to the bodies of two Brazilian TV workers. The two men had gone out to buy a car, but they had bought raincoats instead, even though the day was hot and sunny, with no trace of rain! The police investigator suggested that the workers may have died after making contact with a UFO. One of the pieces of paper had a formula on it, but no one was able to understand it. The police locked the paper in a heavily guarded safe, but when they opened the safe for scientists to examine it, the formula had disappeared!
So could this be even more evidence of life out there?
I’ll leave that one to you to find out…
Part 3 coming soon!
1) One million Earths could fit inside the sun-and the sun is considered an average-size star.
2)For years it was believed that Earth was the only planet in our solar system with liquid water. More recently NASA revealed it’s strongest evidence yet that there is intermittent running water on Mars,too!
3)Comets are leftovers from the creation of our solar system about 4.5 billion years old-they consist of sand ,ice and carbon dioxide.
4)You wouldn’t be able to walk on Jupiter, Saturn, Uranus or Neptune because they have no solid surface!
5)If you could fly a plane to Pluto the trip would take more than 800 years! By the time you got there you would be bones and ashes! WOW!!!
There is a lot to know about the place that holds planets.Space.I hope you find this interesting. 1]A total eclipse is rare and when it happens 90 percent of the sun gets covered by the moon leaving 10 percent of the sun. 2]Astronauts wear spacesuits because there is no gravity and a spacesuit is strong enough to keep them onto a planet and also to breath. 3]There are a total of 9 planets in the solar system/Sun,Earth Neptune, Mars,Saturn,Pluto,Venus,Moon,Uranus. 4]The first ever people to land on the moon were called Neil Armstrong and Buzz Aldrin. 5]The date they landed on the moon was July 20th 1969.
Here are a few facts on space.
- The first men to land on the moon were the famous American astronauts, Neil Armstrong and Buzz Aldrin.
- Our planets were named after Roman gods. Venus, Mercury, Neptune and Jupiter are some of them.
- An eclipse happens when the moon crosses the path of the sun causing darkness. A solar eclipse is when the moon doesn’t fully block out the sun, but makes it darker than usual. A total eclipse is when the moon fully blocks out the sun making it look like night time. Eclipses don’t often happen.
- The sun is a big star. It is made out of lava and fire. If you get within 100 miles from the sun, you will burn.
- Mars is also known as the red planet as it is red all over.
- On Jupiter, a year is only 128 days.
