how many planet are in our solar system
Solar System The Solar System[a] is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.[b] Of the objects that orbit the Sun directly, the largest eight are the planets,[c] with the remainder being smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.[d]

Mercury (planet) Mercury is the smallest and innermost planet in the Solar System. Its orbital period around the Sun of 88 days is the shortest of all the planets in the Solar System. It is named after the Roman deity Mercury, the messenger to the gods.
Jupiter Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two-and-a-half times that of all the other planets in the Solar System combined. Jupiter and Saturn are gas giants; the other two giant planets, Uranus and Neptune are ice giants. Jupiter has been known to astronomers since antiquity.[13] The Romans named it after their god Jupiter.[14] When viewed from Earth, Jupiter can reach an apparent magnitude of âˆ’2.94, bright enough for its reflected light to cast shadows,[15] and making it on average the third-brightest object in the night sky after the Moon and Venus.
