Valentine is a M-Dwarf star and the parent star of the Valentine System. It is the first and only star in Extrasolar, and has five planets: Heba, Solyth, Fust, Mir and Lomina; orbiting around it. Valentine is utterly massive containing 99.6% of the mass in the Valentine system. As with Kerbol, it is not possible to land on Valentine - instead, the craft is simply destroyed.

In-Game Description

Valentine is a small red dwarf star, orbiting about the much larger and brighter star Kerbol. For much of history, most kerbal astronomers assumed that Valentine was just another twinkling star in the night sky. It wasn't until after the distance between Valentine and Kerbol was calculated that astronomers began considering the idea that Valentine might be orbiting around Kerbol. Valentine has several confirmed exoplanets orbiting it, several of which might be Kerbin-like.

Characteristics

Valentine is a small star with less than half (~44 %) the radius of Kerbol. It is classed as a red dwarf, one of the smallest type of stars in the universe. The light and heat from Valentine is much less than what Kerbin experiences from Kerbol on a daily basis. Therefore, all of the planets orbit closer to their star than what they would be around Kerbol. Valentine's photosphere lacks sunspots, which is rather unusual for such a small star. However, its "surface" is shifting and broiling with activity, suggesting that Valentine is younger than the Kerbol system.

System

Valentine has 5 planets in its orbit. Three of those worlds have moons, and one planet hosts life.

  • Heba, a large gas giant orbiting very close to Valentine.
  • Solyth, an arid desert world devoid of life with an oxygen-rich atmosphere.
  • Fust, a planet very similar to Kerbin with a very oxygen-rich atmosphere, large seas, and many islands.
  • Mir, an icy planet with a thick atmosphere.
  • Lomina, a blue-eccentric gas giant with a ring system and five moons.

Synchronous Orbits around Heba, Solyth and Fust are impossible, as they all lie outside the Sphere of Influence of the planets.
