What is the solar system diameter in a million kilometers
No, Mercury is not one of the biggest planets in the solar system. It is the smallest planet in our solar system, with a diameter of about 4,880 kilometers.
The Sun diameter is 1,390,000 kilometers and it is the largest object in the solar system. Amazingly its mass corresponds to 99.8% of the total mass in the solar system.
The Earth is considered big in comparison to other planets in our solar system. It has a diameter of about 12,742 kilometers (7,918 miles) and a surface area of 510.1 million square kilometers (196.9 million square miles).
Jupiter has a diameter of 86,881 miles (139,822 kilometers), making it the largest planet in our solar system.
Mars has a diameter of about 6,779 kilometers (4,212 miles), which is roughly half the size of Earth. Its total surface area is around 144.8 million square kilometers, making it the seventh-largest planet in the solar system.
The diameter of Mercury is 3,032 miles, or 4,879 kilometers. Mercury is the smallest planet in the Solar System and the closest to the Sun.
The largest planets in our Solar system are:Jupiter - which has a mass of 1899x1024 kg and a diameter of 142,984 km.Saturn - which has a mass of 568x1024 kg and a diameter of 120,536 km.Uranus - which has a mass of 86.8x1024 kg and a diameter of 51,118 km.Neptune - which has a mass of 102x1024 kg and a diameter of 49,528 km.
Mercury, because it is the smallest planet in our solar system
Mercury is far smaller with a diamter of about 2,400 kilometers. It is the smallest planet in the solar system while Jupiter is the largest with a diameter of about 70,000 kilometers.
The largest mountain in our solar system is Olympus Mons on Mars.
Very, very, very small. The Milky way is about 100 000 light years in diameter, the Solar system is about 10 light hours in diameter. The diameter of the Galaxy is thus about 90 000 000 (ninety million) times bigger than the diameter of the Solar system.
Mars is about 6,800 kilometers (4,200 miles) in diameter, making it the second smallest of the eight planets in our solar system, and the eighth largest object in the solar system if you include the sun.
