There is no other star that revolves around our sun. There are, however, many double and triple star systems in the universe, where the stars in the system revolve around each other.
The planets revolve around the sun each year. The year for each planet is different because it either takes the planet longer or shorter to get around the sun than other planets. The year of each panet is mesured by how many Earth days or years it takes to get around the sun.Length of Planetary Year in Earth Days/Years:Mercury: 88 daysVenus: 225 daysEarth: 365.25 daysMars: 687 days or 1.88 yearsJupiter: 4,331.5 days or 11.86 yearsSaturn: 10,832 days or 29.46 yearsUranus: 30,799 days or 84 yearsNeptune: 60,190 days or 165 yearsPluto (dwarf planet): 90,410.5 days or 247.7 years
