In july of 1999 a planet was reported to be orbiting the sun-like star iota horologii with a period of 320 days. find the radius of the planet's orbit, assuming that iota horologii has the same mass as the sun. (this planet is presumably similar to jupiter, but it may have large, rocky moons that enjoy a relatively pleasant climate.)

Explanation:

To solve this problem we need to apply Kepler's third law.

Kepler's third law tells us that

Where

T= 320Days ( Period)

r = radius

G =   Gravitational constant

M = Mass of the object, sun in this case

Then,

We need to re-arrange for R, so

Replacing

Therefore the radius of the star is

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
