the mercury relates to the planet earth
Earth is the third closest planet to the sun.
There is not fifth planet on Earth, since Earth is a planet...
We live on it, Earth.
Earth is a closed system in terms of matter, meaning that no new matter is added from outside the system. Matter can cycle within the Earth's systems (such as the water cycle or carbon cycle), but it does not enter or leave the planet.
Oxygen exists if you are on planet earth in any space that has air. The same amount of oxygen exists in a room with a closed door as in a room with an open door.
Earth.
The earth is the only planet on earth.
Earth is the third planet from the sun.
The Earth is essentially a closed system in terms of matter because very little matter enters or leaves it. While energy from the sun does enter the Earth, matter such as air, water, and rocks primarily remain on the planet. However, the Earth is not a closed system when considering energy because it receives energy from the sun and releases energy back into space.
the planet we live on is earth

Early Earth was likely an open planet, with gases and materials escaping into space due to the planet's lower gravity and lack of a protective magnetic field. This allowed for the loss of volatile elements and the input of materials from the surrounding space, shaping the composition and atmosphere of our planet over time.
The closest planet to the Moon is Earth. The Moon is Earth's natural satellite and is closest to our planet in terms of distance.
Planet earth is the only planet that we know of that has life on it.
