The table below shows relevant data in relation to the sizes of the planets. Note, however, that planetary sizes can be measured in different ways; i.e. by mass or volume (circumference/diameter).

Planet	Mass	Mass in relation to Earth	Density	Circumference at the equator	Diameter at the equator
Mercury	3,302×1023 kg	0,055	5,43	15,329 km	4,879 km
Venus	4,8685×1024 kg	0,815	5,24	38,025 km	12.104 km
Earth	5,97219×1024 kg	1	5,52	40,075.16 km	12,756.1 km
March	6,4185×1023 kg	0,107	3,94	24,343 km	6,794 km
Jupiter	1,899×1027 kg	317,83	1,33	439,263.8 km	139.822 km
Saturn	5,6846×1026 kg	95,152	0,70	378.675 km	120.536 km
Uranus	8,6832×1025 kg	14,536	1,30	159,354.1 km	51.118 km
Neptune	1,0243×1026 kg	17,15	17,204	154,705 km	49.244 km
