Deimos is the 2nd moon from Mars. Deimos distance from mars is 23,460 km (14,580 mi). Deimos has a synchronous rotation. Phobos always shows its same face to Mars. Deimos average orbital speed is 1.35 km/s 4860 km/h (3,019.86 mph). Deimos orbits around mars in 1 day 6 hours and 18 minutes. Deimos rises in the east every 5 days 8 hours 7 minutes and 17 seconds.
Deimos apparent magnitude is 12.4 ok! Deimos is 88,715.6 times fainter than Vega(0.03 magnitude) Deimos is 13,427,649,400 times fainter than our full moon(-12.92 magnitude) Deimos albedo 0.068 Deimos absorbs 93.2% sun light just like asphalt. Deimos is very similar to those of C- or D-type asteroids. Deimos diameter or Deimos Dimensions are 15 km (9.3 mi) × 12.2 km (7.6 mi) × 10.4 km (6.5 mi) Mean radius 6.2 kilometres (3.9 mi)
This is how big the space station and Apollo 11 would look compared to Deimos.
Deimos volume is ~(1,006 ± 10) km3 Deimos mean density is 1.471 g/cm3 Deimos mass is 1.48 × 1015 kg Deimos escape velocity is 20 km/h (12.4 mph) Deimos surface gravity is 0.0039 m/s2 ok!A 200 pound person would weigh 1.3 ounces (36 grams) If Deimos had an object in free fall or have its own moon, an object that is 4.65 miles from the center of Deimos, it would take 11 hours and 21 minutes to go around Deimos. And the object would go 2.57 miles an hour.
