First things first, the Moon orbits the planets and the planets orbit the Sun.
The gravity of the Sun keeps all the planets in their orbits, just like the planets gravity keeps the Moons in their orbits.
An orbit is a journey/path that an object takes in space. For example, stars, planets or moons.
Gravity is the pulling force that works in space.
The closest planet to Earth is Venus. Some call it our twin sister, because it is almost the same size and is made up of the same kinds of rocks and metals as Earth. Although it is not a good home for humans.
Venus is named after the Roman goddess of love.
On Venus it is forever cloudy and the sky is orange.
The atmosphere on Venus is like a high pressure cooker made of poisonous gases. Visitors would shrivel up in seconds and roast like a potato.
Astronomers call Venus the morning or evening star, because the light from the Sun bounces of the thick clouds on the planet, so it often looks like a big bright star in our sky, just before sunrise and after sunset.
There are no seas, rivers or oceans on the surface of Venus.
Even though Venus is not as close to the Sun as Mercury, it is much hotter with temperatures hitting up to 464 degrees Celsius, even at night due to its poisonous gases.
Venus has a rocky surface because it has been shaped by volcanic eruptions
Venus has a cloudy and swirling atmosphere similar to Earth, except for it is burning hot and poisonous.
The yellow clouds in the sky of Venus are full of a harmful acid. If it rained it would burn your skin.
A Venus year is shorter than ours. Where we have 365 days in a year, Venus has 225. But the really amazing thing about Venus is the length of its days, which last for 243 Earth days, which means a Venus day is actually longer than a Venus year.
A space probe called Magellan, made up from spare parts from the Viking, Voyager, Galileo and Ulysses space probes, which was working till 1994, helped scientists make a map of Venus’s surface.
The Magellan craft saw that Venus had monstrous volcanoes and jagged mountains just like Earth. Maat Mons is one of the largest volcanoes on the planet.
The surface pressure on Venus, is about the same as you get a kilometer under the oceans here on Earth.
N.A.S.A have recommended sending astronauts there in the future using airships. The mission is called “HAVOC” for short. High Altitude Venus Operational Concept.
Venus has been visited by a handful of spacecrafts despite its perils. The first to arrive was the Soviet, Venera 9 probe in 1975. It only lasted 53 minutes, but enough time to send back the first photographs of the surface.
A space probe is a robotic spacecraft that explores into outer space.
The longest any probe has survived on the surface is about 2 hours. Humans are unlikely to pay a visit to Venus, unless there is a radical change in materials science.
Venus has the longest rotation period of any planet in the Solar System and rotates in the opposite direction to most other planets.
Venus is the second planet from the Sun and it orbits it every 224.7 Earth days.
Venus is the only planet named after a female.
Venus along with Mercury have no moons.
