If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API is the American Petroleum Institute. WTI Crude API gravity of around 39.6. Brent Crude has an API gravity of around 38.06. OPEC basket of oil from 7 countries is the sourest, At present the API gravity for the Basket is heavier, at 32.7. Location: Brent Blend is a combination of crude oil from 15 different oil fields in the North Sea. It is less âlightâ and âsweetâ than WTI, but still excellent for making gasoline.
The first telescopic observation of Mars was by Galileo Galilei in 1610. Within a century, astronomers discovered distinct albedo features on the planet, including the dark patch Syrtis Major Planum and polar ice caps. They were able to determine the planet's rotation period and axial tilt.
The Radius of Mars is 3,389.5 km (About half of the radius of the Earth). Its circumference is 21,344 km (Not a big surprise, this is also about half of the circumference of the Earth). The volume of Mars is 1.63116 X 10 11 km 3 and the mass of Mars is 6.4169 x 10 23 kg. Although Mars is smaller than Earth its surface area (38% of earth) Is Almost identical to earth LAND space (Since there are no oceans on Mars). A common hoax is about the moon and Mars being equal in size. The hoax started back in 2003 when in august 27th Mars was in opposition to earth (Minimal distance) of about 55 Million KM.
