"15 Things You Didn’t Know About Earth"-1

Today's blogs are going to be all about our planet earth.
We count 15 facts about the little blue planet we like to call home.In this blog i have explained the first three facts.

1 – 24 Hours,
The common saying goes that there’s only 24 hours in a day – but that isn’t actually true, the Earth spins on its axis for 23 hours and 56 minutes
The reason we add an extra 4 minutes is because the distance in which we’ve orbited the sun is so great that it takes some extra time just for us to face the sun again
And since the Earth is spinning slower and slower every few million years, in around 250 million years a typical day will actually last 1.5 hours longer

2 – Gravity Glitch,

There is an area in Canada known as Hudson Bay with uneven mass – and where there’s uneven mass, there’s uneven gravity
Long-since melted glaciers once lined the area, but now they’re gone and the burden of gravity remains in both the ice sheets and underneath the Earth’s crust, leading to lower gravity here than anywhere else on Earth
Don’t get too excited though – it’s not like you’ll be able to start moon-jumping around Canada – the difference in gravity is only a 0.005% reduction, so minute that you can’t even feel it

3 – Photo,

65 miles above the atmosphere, the first ever photo of Earth was taken with a camera carried by a V-2 missile in 1946 – it snapped a frame every second and a half and managed to survive re-entry
The scientists who reviewed the footage were beyond ecstatic, jumping up and down with joy that they could finally see their own world in a still image
Likewise in 1967 the first full-on, colour Earth image was taken by the DODGE satellite
