Question

suppose earth is totally circular in shape than that will happen and what changes we are going to see campers to now ??????​

Answer 1

Answer:

Kepler's law applies to planetary orbits, whether they be of circular, or elliptical shape. It says that

T

2

1

T

2

2

=

R

3

1

R

3

2

where T is the period of an orbit and R is its semi-major axis. The semi-major axis is the average of the planet's maximum and minimum distances from the sun.

Let the earth's mean radius be R

1

..This straight fall can be considered 1/2 of a degenerate elliptical orbit with major axis equal to R

1

. Its semi-major axis is

2

R

1

(the average of R1 and zero). Its period will be designated T

2

.

So:

T

T

=

R

(

And therefore, T

=0.353 year, and the time to fall into the sun is the time to fall into the sun is ,64.52 days
