The fifth planet from the Sun is Jupiter. This classification is based on the arrangement of the planets in our solar system, which follows a specific order determined by their distances from the Sun. Starting from the Sun, the order of the planets is Mercury, Venus, Earth, Mars, and then Jupiter.

Jupiter is well-known as the largest planet in our solar system, boasting a significant size that is more than 11 times the diameter of Earth. It is a gas giant, composed mainly of hydrogen and helium, and is famous for features such as the Great Red Spot, which is a massive storm larger than Earth itself.

Understanding the order of the planets is essential in astronomy, as it provides context for studying their characteristics, atmospheres, and potential for hosting life. Jupiter, in particular, plays a crucial role in the stability of the solar system, influencing the orbits of other celestial objects due to its strong gravitational pull.
