What exactly do we know of our neighbour planets ?




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 rocky crust.

Because it is so close to the Sun, it is very difficult to see Mercury. A NASA mission called Messenger is expected to begin orbiting the planet in 2011. It is expected that this will help us learn a great deal more about this rarely seen planet.





Space The Messenger launched on the Boeing Delta II rocket on August 3, 2004. It will reach Mercury on March 18, 2011.

Facts about Mercury


Mercury's winged helmet.

Mercury was a god in Roman mythology. He was a messenger with winged feet.

Diameter:

3,032 miles (4,879 km).

Distance from Sun

Venus
Of all the planets, Venus is the one most similar to Earth. In fact, Venus is often called Earth's “sister” planet.Personally I believe something happened on Venus that made human run and stay here . Though 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. Both planets are relatively young, judging from the lack of craters on their surfaces


We now know that the environment on Venus couldn't support life as Earth does. Our atmosphere is a breathable mix of oxygen and other gases, but the atmosphere on Venus is mostly carbon dioxide, which is a poisonous gas. The temperature on Earth rarely goes much higher than 100° F (37.8° C), even at the equator, but the temperature on the surface of Venus can exceed 850° F (454° C)!

Space The atmosphere of Venus would be compared to the exhaust from a car.



The Earth is mostly water, but whatever water that may have existed once on Venus has boiled away due to the intense heat.

Facts about Venus

The same as the gender symbol for female.

Origin of name:

Venus was the Roman goddess of love and beauty.

Diameter:

7,520 miles (12,100 km).

Distance from Sun:

About 67 million miles (108 million km).

Length of year:

225 days.

Number of Moons:

None.

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. It is believed to be about 4.5 billion years old, which makes it very young compared to other celestial bodies!




Facts about Earth


A circle with an equator and a meridian line at right angles.

Origin of name:

Probably from the Old English word that means “soil.”

Diameter:

7,926 miles (12,755 km).

Distance from Sun:

93 million miles (150 million km).

Length of year:

365 days.

Number of Moons:

One.

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.


Does this all mean you need to be concerned about an alien attack from Mars? Hardly. Still, as we learn more and more about the final terrestrial planet, the more mysterious and wonderful Mars becomes.

Facts about Mars

The gender symbol for male.

Origin of name:

Named after Mars, the Roman god of war, perhaps because of the planet's red color.

Diameter:

4,217 miles (6,786 km).

Distance from the Sun:

142 million miles (229 million km).

Length of year:

687 days.

Number of Moons:

Two, called Deimos and Phobos.

JUPITER


The planet Jupiter is the first of the gas giant planets. Made mostly of gas,Why? Well it is said if Jupiter was 80 times bigger than it was , it would had become a sun , imagine having the sun inthe afternoon and another in the night,Jupit.

Well gas giants 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.


This giant planet comes in first again when it comes to giving off heat. The core of Jupiter may be made of liquid rock that reaches temperatures of 43,000° F (23,870° C).

There are at least 63 moons of different sizes orbiting Jupiter. That's the most of any planet. Its largest moon is called Ganymede. It has a diameter of 3,400 miles (5,472 km)—larger than Mercury!



Facts about Jupiter

Origin of name:

Named after Jupiter, the principal god in Roman mythology.

Diameter:

88,732 miles (142,800 km).

Distance from Sun:

484 million miles (779 million km).

Length of year:

Almost 12 Earth years.

Number of Moons:

63.

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!

Space

Space The Hubble telescope captured this image of Uranus with its rings and some of its moons.

Facts about Uranus


Origin of name:

Comes from Ouranos, the Greek word for “sky.”

Diameter:

About 32,200 miles (51,819 km).

Distance from Sun:

1,783,940,000 miles (2,870,894,600 km).

Length of year:

84 Earth years.

Number of Moons:

21.

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.

It is the most distant planet from the Sun. It takes a very long time—165 years—to orbit the Sun. Neptune has made only one trip around the Sun since it was discovered.



Facts about Neptune
Astronomical Symbol. :Neptune's trident.

Origin of name:

Ancient Roman god of the sea, often pictured holding a trident (a spear with three sharp prongs).

Diameter:

30,777 miles (49,529 km).

Distance from Sun:

2,795,084,800 miles (4,498,033,400 km).

Length of year:

About 165 Earth years.

Number of Moons:

13.

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


Facts about Saturn
Astronomical Symbol:

Believed to represent the scythe of the god Saturn.

Origin of name:

Saturn was the ancient Roman god of agriculture.

Diameter:

74,900 miles (120,537 km).

Distance from Sun:

888 million miles (14,290 million km).

Length of year:

29.5 Earth years.

Number of Moons:

At least 56.

Great job, man.

I heard the "Great Red spot" is gradually fading away. In the next 20 years, it could all be gone and gone for good.

You heard that news as well, right?

I thought it would stay centuries still but of course most of the statistics would vary greatly.

Another fun fact about Venus is it has an atmospheric pressure 100 times that of earth, and would basically crush any human.
And the Soviets landed drones on it, for a brief period and were able to take pictures of its surface.

I really hope so.
Thank you so much! I appreciate you!!
But how to speak and read is still very very poor

Live - action? No, I didn't watch it.
I didn't even read manga or watch that Anime. Interesting?
