So we are back again and continuing the space for kids series, this will be the last article for this series so thoroughly enjoy it. Who knows, your kid might ask you the Questions about planets?

Mercury

1. On which planet would you roast during the day and freeze at night?

Mercury. When the sun is shining, the temperature on Mercury reaches 800 degrees Fahrenheit(426°C). But at night the temperature drops sharply to nearly -300 degrees(-184° C). That’s the difference of more than 1100 degrees Fahrenheit(600°C)! Mercury has no air around it. That means no winds blow. Over billions of years, lots of rocks form space have crashed into Mercury. Each one left a hole, a crater, that still looks exactly as it did when it was formed.

Venus

2. Which planet is buried under thick clouds?

Venus. But the clouds are not like the clouds around Earth. Venus’s clouds are bright yellow and they are poisonous. The planet is also the hottest planet at all. The 900 degrees Fahrenheit(482°C) temperature at its surface is hot enough to melt metal!

The sun shining on Venus makes the planet looks very bright to us on Earth. Because it shows up just before sunrise or after sunset, people call Venus the “morning star” or the “evening star”– a name it got before anyone knew the difference between a star and a planet.

Mars

3. Why is Mars red?

Because the surface of Mars is covered with rocks that contain lots of iron. The iron has rusted. And as you know, rusted iron is red in colour.

The surface of Mars is like a dry, rocky desert. In 1997 the Pathfinder spacecraft found the part of Mars was once flooded with water. Now the only water on the planet is frozen in ice caps around its North and South pole.

Jupiter

4. Which is the biggest planet?

Jupiter. The diameter of Jupiter is more than 10 times the diameter of Earth. More than 1,000 planets the size of Earth could fit inside Jupiter. A plane trip around Earth’s equator would take about 40 hours. The same trip around Jupiter’s equator would take 200 hours.

While Mercury, Venus, Earth, and Mars mostly rocks, Jupiter–as well as Saturn, Uranus and Neptune is mostly gas with some liquid. Only the central core is solid. And while Earth has 1 moon, Jupiter has 16 moons.

Saturn

5. Which planet is known for its beautiful rings?

Saturn. Seven rings made of chunks of ice and rock revolve in orbit around the planet. The rings are very wide–but very flat. They are so thin that astronomers can see distant stars through them. Yet the rings are heavy enough to cast shadows on Saturn.

Saturn has 18 moons. That is more than any other planet in our solar system. The largest moon, Titan is the only moon in our solar system with an atmosphere.

Uranus

6. Which planet spins on its side?

Uranus. It rotates like the other planets. But this planet is tilted way over. It looks like a top spinning on its side.

Through a telescope, we can see the rich blue-green colour of Uranus. The color from gases in its atmosphere.

We can also see the 11 rings that astronomers found around Uranus in 1977. They are like the rinds around Saturn but are less visible because they are made up of dark chunks of matter.

Neptune

7. Which planet is eighth from the sun?

Neptune. Astronomers knew Neptune was there before they actually found it. There were signs that another planet was pulling on Uranus’s orbit. The scientist looked around–and that’s how they found Neptune.

Through powerful telescopes, Neptune looks like a small, blue circle with a large spot as big as Earth. The spot is thought to be an area of strong storms that come and go. Neptune is a very cold planet since it is far from the sun–about 30 times farther out than Earth!

Pluto

9. Is Pluto really a planet?

No. In 2006, astronomers redefined Pluto as a dwarf planet, which is different from a planet. A dwarf planet is a round body that orbits but has no near neighbours. Astronomers have already found two other dwarf planets.

The surface temperature of Pluto is around–400 degrees Fahrenheit(-240°C). And its size is smaller than Earth’s moon.

Pluto is never closer than almost 3 billion miles(4.8 billion km) from Earth.

Earth

10. How long is a day of each planet? How long is a year?

A day is a time it takes a planet to rotate once. Earth takes 24 hours. Since each planet rotates at a different speed, the length of the day varies from planet to planet.

A year is a time it takes a planet to revolve once around the sun. Earth takes 365 days or one Earth year. Since each planet is at a different distance form the sun and each travels at a different speed, the length of a year form planet to planet.
