Not exactly. Assuming that by "the sun" you mean
our sun, Sol is an average bright yellow main sequence star of spectral class G2. The "main sequence" ranges from the incredibly large, hot, and bright blue-white O series stars such as Orionis C (30000 times brighter than the sun) to small, red, and dim M series red dwarf stars like Wolf 359. The spectral classes of the main sequence are O B A F G K M - the mnemonic is "Oh, Be A Fine Girl, Kiss Me."
As our sun nears the end of its main sequence "life," it will use up most of the lightweight hydrogen fuel that feeds its fusion furnace. At some point it will balloon out into a red giant star, very hot and with a radius almost to the orbit of Venus. It will continue that way for several million years, consuming heavier elements and growing weaker and cooler. As it starts to run out of even the heavier elements to burn, it will become a "nova" or "new" star. It will shed the outer layers of gas to form a "planetary nebula" surrounding a hot white core not much larger than planet Earth. This super-dense hot white core is called a white dwarf. After several million more years, the white dwarf will burn out, leaving a solid tombstone in space - a brown dwarf (sometimes called a black dwarf).
The stars and planets in Freelancer are all much, much smaller and closer together than they would be in real life. Think about it - standing on the Earth and looking out into our solar system, Mars, Venus, Jupiter, and Saturn are visible with the naked eye but appear no larger than bright stars. In the Low Earth Orbit that the space shuttle uses, it takes about an hour and a half to go around the planet once, traveling at 19000 miles per hour.
Thus endeth the astronomy class for this evening. Be sure to tune in next week for a seminar on black holes, quasars, and cepheid variable stars.
