Solar

Solar is an M-Class red dwarf star situated in the Lylat System. Surprisingly, it was the site of several battles during the Lylat Wars and afterwards.

Overview
Solar is situated in the middle of the "X-Y-Z Triangle", a geometric shape formed by the locations of Sector X, Sector Y and Sector Z.

With its surface temperature around 3,500 K*, this red dwarf star is one of the coolest stars in the galaxy. In comparison, the exact opposite of Solar, a B-Class blue star, has a surface temperature of over 25,000 K. However, because it burns hotter and faster, a blue star has a life expectancy of a couple billion years. Solar burns much slower and so will last much longer; scientists predict it will live for about a hundred billion years, if not more.


 * Solar's surface temperature may be higher than 3,500 K. The Arwings used by Star Fox team are shielded against temperatures up to 9,000 degrees (Centigrade or Fahrenheit is not specified, although 3,500 K is still lower than 9,000 ºF or 9,000 ºC [3,500 K = 5,840.33 ºF and 3,226.85 ºC, to be exact]), but when flying over Solar in Star Fox 64, the team's Arwings will slowly take damage from the star's heat, implying that the star is hotter than 3,500 K, or probably that the Arwing's temperature is slowly rising while flying in Solar so that the Arwing is damaged from constant heat. It is worth mentioning however that the Arwing cannot be killed in Solar's heat however, only stripped down to a point where one hit will kill it.

History
Before the Lylat Wars scientists never believed that life could exist on a star, even one as cool as a red dwarf like Solar; so perhaps Andross introduced life there just to spite his colleagues. Nevertheless, General Pepper sent the Star Fox to investigate when a number of Venomian scout ships were detected approaching and leaving the star. What they discovered were biological monsters, the result of Andross's genetic experimentation, that not only lived but thrived in the extremely hot environment.

The team battled through this hellish environment while fighting creatures like Goreses, while receiving help from Bill Grey. Eventually they were forced to confront Vulcain, the most deadly of Andross's star-spawn bioweapons. Dodging its attacks, Fox McCloud was able to destroy the beast and put an end to Andross' mad biological terror. Life continued to flourish on the star even after the war ended. In Star Fox: Assault, on most planets, you can view Solar by looking up to a big star surrounded by a red ring.

Trivia

 * There is some conjecture as to whether Solar is a star or a planet. In Star Fox Command, it clearly states that Solar is a planet and that there are some solid patches. However, it is in every other instance referred to as a star. It is possible that Solar, like the planet Jupiter in our own star system, is in fact a gas planet that generates some of its own heat but still receives most of its energy from the parent Lylat Star.
 * Red Dwarf stars are one of the weakest class of stars in our known universe and because of its small mass, density and relatively cold temperatures it is extremely unlikely that Solar could support the planets around it both gravitationally and thermally if the Lylat system were a real star system. It is thus possible that the Lylat system could exist as a binary star system (with its parent star being anything greater than an M class star) which are also much more common in our galaxy than single star systems.
