Create three fictitious stars, with plausible numbering based on existing star catalogs, with a spectral type and luminosity class randomly selected from one of the following (supergiant (B0 to M5), giant (A5 to M5), main-sequence (B0 to M5), or white dwarf (B3 to K0)), a luminosity in the range between 1e-5 to 1e5 solar units (with the scientific notation coefficient being whole numbers 1, 2, or 5), a temperature between 2,000 K to 50,000 K (with the scientific notation coefficient being an integer or half-integer value) apparent magnitude between -2 and +11, distance between 1 and 10,000 light years. Report today's date and time. Cite the following statistics about this star: (a) Name. (b) Luminosity, solar units. (c) Temperature, in Kelvin. (d) Apparent magnitude. (e) Distance, in light years. Don't use scientific notation. Don't report the spectral type. Don't report the luminosity class. Don't report the size.
