What was Kepler’s conclusion?
He concluded that the Earth does not revolve round the Sun at a uniform rate, and that the Sun is not at the centre of the Earth’s orbit. This led him to the fact that the Earth and the other planets sweep out equal areas in equal times, his second law, which he discovered before his first law.
What are Kepler’s 3 laws in simple terms?
There are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its …
Why does earth revolve around the sun in elliptical?
This is due, for example, to the fact that when the Earth is closer to the Sun in its elliptical orbit it orbits faster, while when it is further away it orbits slower, averaging to a value equivalent to that of a circular orbit. …

Lava is the hottest natural thing on Earth. It comes from the Earth’s mantle or crust. The layer closer to the surface is mostly liquid, spiking to an astounding 12,000 degrees and occasionally seeping out to create lava flows.
What’s the coldest thing on Earth?
A chunk of copper became the coldest cubic meter (35.3 cubic feet) on Earth when researchers chilled it to 6 millikelvins, or six-thousandths of a degree above absolute zero (0 Kelvin). This is the closest a substance of this mass and volume has ever come to absolute zero.
