In 500-900 million years, increased surface temperatures will accelerate the inorganic CO² cycle, reducing it to lethally low levels for plants.
Within 1 billion years, all water will be gone and the average surface temperature will reach 70 °C (158 °F).Earth is expected to be effectively habitable for about another if the nitrogen is removed from the atmosphere.Above the Arctic Circle, an extreme case is reached where there is no daylight at all for part of the year – up to six months at the North Pole itself, which is known as a “polar night”.In the southern hemisphere, the situation is exactly reversed, with the South Pole experiencing a “midnight sun” – i.e. This will result in a serious shift in Earth’s habitable zone, as the increased radiation will have a dire effect on life and lead to the loss of the oceans.In essence, it is the largest terrestrial planet, but is smaller and less massive than any of the gas/ice giants of the Outer Solar System.
And with a mean density of 5.514 g/cm³, it is the densest planet in the Solar System.In addition to being the birthplace of humanity and the cradle of human civilization, Earth is the only known planet in our Solar System that is capable of sustaining life.As a terrestrial planet, Earth is located within the Inner Solar System between between Venus and Mars (which are also terrestrial planets).We have scoured the internet to share with you our favorite cards to give to your spouse that are funny, witty, clever and yes, even PUNny!

However, other simulations suggest that in time, Earth’s orbit will decay, it will fall into the Sun and be vaporized.
