So here goes, How can we tell a star has a planet.

They are looking for two things.

First the brightness of the star is reduced in a periodic way Just like on earth we can see somewhere on earth when the moon is between us the sun and it is visible to the naked eye every 14 days. To see that far they use the most powerful telescopes on earth. They can amplify the results by using telescopes in different continents which make the telescope to behave like it is a lot larger than it is.

Secodnly, they take the picture of the sky regularly and those stars with planet do something called a wobble. It moves slightly compared to the other stars around it and returns again periodically.

it is a well known practice and a pilot not being aware pf these simple principles tells me you cannot ride a bike never mind flying a plane.

A star’s color is critical in identifying the star, because it tells us the star’s surface temperature in the black body radiation scale. The sun has a surface temperature of 5,500 K, typical for a yellow star. Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star. The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K. Stars are fuelled by the nuclear fusion reactions at their core.

God must have been a nuclear scientist. I wonder which university did he attend?
