What Type Of Star We Feel Is Best

A medium sized yellow star with the spectral type G would be the best candidate for a solar system with an Earth-like planet. Our sun is also a medium sized yellow star with the spectral type G, and It would be best if the star was similar to the Sun. It would be easier for us to become accustomed to, and since we have adapted to our sun, it would be better to find something similar for the continuation of humans.

Why Scheat Is A Good Candidate For A Solar System With An Earth-Like Star

Magnitude/Luminosity

Scheat is an irregular variable, which means it's brightness varies unpredictably . Because of this, it's apparent magnitude varies between 2.1 and 3.0. It's average magnitude is 2.42.

Scheat's luminosity is 340 times that of the sun, not including invisible infrared. Factoring in the infrared rays, the true luminosity is 1500 times that of the sun.

Temperature

Since Scheat is a red giant, it is fairly cool compared to other stars. It's surface temperature is 3689° K

Scheat is a good candidate for a solar system with an Earth-like planet because it is similar to the sun in many aspects. An example of this is the fact that both stars are composed of little helium and neutral metals. As well as their similarities, there are also some differences. The temperature of Scheat and the Sun are quite different. What must be considered however, is the fact that Scheat is much much larger than the sun and an earth like planet would do great with a lower temperature star as long as it was closer to the star, in a goldilocks zone. So the difference in temperature is really not a problem. Scheat is also a good candidate because of it's distance from Earth. It may be far away, but it sure is closer than a lot of other stars out there. Valuable time and money could be saved if Scheat were to be chosen.

Composition

Scheat is classified with the spectral type M, which means it is a reddish color and has a composition of little or no hydrogen, neutral metals, and molecules. The star's outer shell is also in good condition for titanium oxide to form.

Size and Color

Scheat is a star with an orange-reddish hue. It shines very brightly and it's color is quite noticeable from a telescope.

The star is very big, with a solar mass of 2.1 (4.177E30 kg), and it is classified as a red giant.

Distance from the Earth

Scheat is 196 light years away from Earth. That's 1854303172625837 km!

How Scheat Compares to The Sun

Constellation

Scheat is located in the constellation Pegasus, at the northwest corner of the famous great square of Pegasus

Size: with of a mass of 4.177E30 kg, Scheat has a mass about 5 times that of the Sun, with a mass of 1.989E30 kg.

Color: While Scheat is a reddish color, the Sun is a yellowy color.

Magnitude: Scheat has an average magnitude of 2.42, while the sun has a magnitude of -26.74. That's a difference of -24.34.

Luminosity: The luminosity of Scheat is 1500 times that of the Sun. (340 times not including infrared rays.)

Temperature: The temperature of Scheat is 3689° K and the temperature of the sun is 5,778° K. The sun is hotter by 2089° K.

Distance: While the sun is a lot closer to earth with a distance of 149,600,000 km, Scheat is 1,854,303,172,625,837 km away. That's a difference of 1854303023025837 km!

Location: Scheat and The Sun are both located in different galaxies. Scheat is located in Pegasus and The Sun is located in the Milky Way.

Composition: The Sun is classified as spectral type G, so it is composed of still weaker hydrogen and ionized and neutral metals. Scheat is composed of little or no hydrogen, neutral metals, molecules and titanium oxide in it's photosphere. Both have little hydrogen and neutral metals.

The Age of Scheat

Scheat is in the 3rd stage of the star life cycle, it is a red giant. Scheat used to be a star like our sun. Scheat is about 7 billion years old.
