GJ 667 C g exoplanet is located in the constellation Scorpius. It is an exoplanet orbiting the star GJ 667 C, located about 23.2 light-years (7.1 pc) away from Solar System.

According to the Nasa Exoplanet Archieve, its coordinates are RA (right ascension) 17h19m00.25s and Dec (declination) -34d59m51.95s in the sexagesimal system. This data match with the following International Astronomical Union's image of Scorpius constellation:

This exoplanet can not be found at the Light Kurve Calculation, so we are going to calculate its light curve using an alternative.

Open the UnOfficial Chandra Archive Search. There, search the name of the exoplanet and copy the link adress ended in _evt2.fits.gz.

Then, open JS9, click on File, open remote and paste the link adress in the URL section. Next, click on Analysis and later on Light Curve. It appears the following graphic for GJ 667 C g:

Now, we are going to calculate its radius with the unit Earth radius, because it is a super-Earth exoplanet so it is better to compare it with Earth.

As we have worked on base thousand, now we have to divide the result by ten. So then, the result is that __GJ 667 C g has a radius of 2,491 R ⊕__.

According to the Exoplanet catalog of Nasa, the radius of this exoplanet is estimately 1,99 R ⊕.

Furthermore, at the M. Melita et al. Article published on 2016 it is said that GJ 667 C g has a radius of 1.5–1.7 R ⊕.

In conclusion, because of the result of the calculation it can be stated that the light curve obtained from JS9 is correct, but not as exact as the one obtained at the Light Kurve Calculation. The results obatined from it do approximately match with the results that scientists had obtained.

The calculation of the mass can be made from the calculation of the slope of the linear regression graphic of Terran worlds.

For the calculation of the mass, it has been used our own radius data obtained previously and the radius data obtained by scientists.

We obtain that the result is that __GJ 667 C g has a mass of 8.78 M ⊕__.

Searching weather the data is the same as the scientific articles at Scholar Google, we obtain that this data does NOT correspond with Guillem Anglada-Escudé et al. Article in which it is said: "The 28 day signal implies a planet candidate with a minimum mass of 4.5 M⊕ orbiting well within the (...).

The difference between these values is very relevant. So at the same picture there is the same calculation but instead of using our own radius data, it is used the radius data obtained by scientists. Now, We obtain that the result is that __GJ 667 C g has a mass of 5.15 M ⊕__.This data approximately corresponds with the data obtained by scientists.

Even dough, we can NOT state whether that the light curve obtained from JS9 is correct. The previous results obatined from it approximately match with the results that scientists had obtained. But this data is invalid, because as its mass is greater than 2 M⊕ it is not a Terran world. So the linear regression graphic is not the one in which we had calculated the slope used for the calculation of this mass. We must calculate the slope of the Neptunian worlds to calculate its mass.

K2-24b (also known as EPIC 203771098 b) is an exoplanet orbiting the star K2-24 every 21 days. It is a gas giant exoplanet is located 560 ± 2 light-years (171.6 ± 0.5 pc parsecs) away from Solar System in the constellation of Scorpius.

According to the Nasa Exoplanet Archieve, its coordinates are RA 16h10m17.63s and Dec -24d59m26.17s in the sexagesimal system.

Light curve calculation results:

Calculation of the Radius. We are going to use the units Earth Radius (R ⊕).

As we have worked on base thousand, now we have to divide the result by ten. So then, the result is that __K2-24 b has a radius of 4,839 R ⊕.__

According to the Exoplanet catalog of Nasa, the radius of this exoplanet is estimately 5.83 ± 0.60 R ⊕.

Moreover, at the Erik A. Petigura et al. Article published on 2016 it is said that K2-24 b has a radius of 5.68 ± 0.56 R ⊕.

The calculation of the mass can be made from the calculation of the slope of the linear regression graphic of Terran worlds.

For the calculation of the mass, it has been used our own radius data obtained previously and the radius data obtained by scientists.

We obtain that the result is that __K2-24 b has a mass of 42.65622689 M⊕__.

Searching weather the data is the same as the scientific articles at Scholar Google, we obtain that this data does NOT correspond with Erik A. Petigura et al. Article in which it is said: "K2-24 b (...) has a mass of 21.0 ± 5.4 M🜨".

The difference between these values is very relevant. So, it can be stated that this result is invalid because as its mass is greater than 2 M⊕ it is not a Terran world. So the linear regression graphic is not the one in which we had calculated the slope used for the calculation of this mass. We must calculate the slope of the Neptunian worlds to calculate its mass.
