🌍Earth🌎
✨The third planet out from the Sun, the Earth, is 149.6 million km away on average.
✨The Earth is the fifth largest planet in the Solar System, with a diameter of 12,756 km and a circumference of 40,075 km at the equator.
✨The atmosphere is mostly harmless nitrogen and life giving oxygen, and it is over about 200km deep. The oxygen has been made and maintained by plants over billion of years.
✨The magnetic field, stretching 60,000 km out in to space, protects Earth from the Sun's radiation.
✨The Earth formed 4.55 billion years ago from clouds of space dust whirling around the young sun. The planet was so hot that it was molten at first. The surface cooled slowly in to a hard crust.
✨The Earth orbit around the Sun is 940 million km in length and takes 365.242 days.
✨Although the Earth is tilted at an angle of 23.5 degree, it orbits the Sun on a level plane- the plane of ecliptic.
✨The Earth is made up of the same basic materials as meteorites and the other rocky planets- mostly iron(35%), Oxygen(28%), silicon(17%), magnesium(15%) and nickel(2.7%).
