Its mean diameter in miles is around 525 miles (844km). Astronomers are unsure of its shape as it is so small and far away, so it remains a dwarf planet candidate. If it turns out that it is approximately spherical in shape, then it is likely to be classified as an official dwarf planet.
No known planet in our solar system is about 1 million miles wide. The largest planet, Jupiter, has a diameter of about 86,881 miles. The largest known dwarf planet, Eris, has a diameter of about 1,445 miles.
A black dwarf is not a planet; it is the remnant of a long dead star that has cooled. A black dwarf would range from about 7,000 to 17,000 miles in diameter.
The dwarf galaxy is about 8,000 miles in diameter.
The biggest dwarf planet in our solar system is Pluto. It was considered the ninth planet until 2006, when it was reclassified as a dwarf planet by the International Astronomical Union. Pluto has a diameter of about 1,473 miles (2,370 kilometers).
An average dwarf galaxy is small in diameter.
Ceres, a dwarf planet located in the asteroid belt between Mars and Jupiter.
The planet you are referring to is Jupiter, which has a diameter of approximately 86,881 miles. Mercury has a diameter of about 3,032 miles, Venus has a diameter of about 7,521 miles, Earth has a diameter of about 7,917 miles, and Mars has a diameter of about 4,212 miles.
Here are the planets diameter in kilometers. Mecury:4,880 Venus:12,104 Earth:12,756 Mars:6,794 Jupiter:142,984 Saturn:120,536 Uranus:51,118 Neptune:49,532 Pluto:2,274 Hope this helps!
Pluto's diameter is 2374 kilometers. or 1,475 miles. Pluto has about the same amount of land as Russia.
The dwarf planet Pluto is located about 3.67 billion miles from the Sun.
Ceres (designated as 1 Ceres) has an average diameter of about 950 km (590 miles). It is by far the largest object in the asteroid belt. It is, however, the smallest dwarf planet. By comparison, Pluto has a diameter of about 2300 km (1430 miles).The asteroid is slightly oblate, but apparently not because of rotation. Its polar diameter is only about 909 km (565 mi) while its equatorial diameter is about 975 km (606 mi). NASA lists the "average" diameter as 930 km (580 mi).
It was once considered the fifth planet, then it was changed to asteroid, and is currently (since 2006) considered a dwarf planet (the smallest one yet, only 590 miles, or 950 km, in diameter)Hope that helped:)
