An average dwarf galaxy is small in diameter.
The dwarf galaxy is about 8,000 miles in diameter.
600,000 trillion.
some 100,000-120,000 light-years in diameter, which contains 100-400 billion stars
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.
The Andromeda Galaxy is approximately 220,000 light-years in diameter, which is equivalent to about 1,294,833,160,000,000 miles.
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).
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).
The Tadpole Galaxy, also known as UGC 10214, has an estimated diameter of about 280,000 light-years. This translates to roughly 1.6 million trillion miles. The galaxy is notable for its long tidal tail, which is a result of gravitational interactions.
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.

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.
Mars has an average diameter of about 4,220 miles.
