HD 7924 b | Erasmus +

I have searched for exoplanets in my constellation and I have discover some of them like HD 7924 b or HD 219134 b. I decided to analyse HD 7924 b, an exoplanet that orbits around the star HD 7924. There are two more exoplanets orbiting this star. Here you can see and manage a real model of the planet and the star.

I have found this graphics that show the light curve of the exoplanet. We can see that both are similar.

They show the brightness of the star over a period of time. When the line goes down, the exoplanet is in front of the star and its brightness decreasses.

We can see that the brightness variation is 0.0004.

Doing some research about the exoplanet and its star I have found this data:

HD 7924 B
Radius	1.05 RJ
Mass	6.3566 Earth
Orbital Period	5.39792 (± 0.00025)
Temperature	826.0 K

HD 7924
Distance	16.8 (±0.1) pc
Spectral type	K0V
Apparent magnitude	7,185
Mass	0.832 (±0.036) M_Sun
Radius	0.78 (± 0.02) R_Sun
Temperature	5177.0 (± 44.0) K

Then, I have calculated the speed of the planet using the formula of Laboratory for the study of exoplanets.

According to my calculations, the speed of the planet is 3,72 Earths/AU.
