Ceres, which is not truly a planet, has no atmosphere and therefore no wind.
As far as we know, Haumea does not have an atmosphere, so the wind speed would effectively be zero.
An anemometer is used for measuring the speed of wind,
No. A wind vane is an instrument that can tell wind speed but not wind direction.
The current wind speed on the wind speed chart is 40 kilometers per hour.
wind speed = squrt(u^2+v^2).
Wind speeds on Eris are estimated to be extremely low due to its distance from the sun and its minimal atmosphere. However, exact wind speed measurements are not available as there have been no direct observations made on the dwarf planet.
An anemometer measures the wind speed, and a windvan measures wind direction.
Wind speed is measured with an anemometer.
By the types of sails that you have. or it could be the wind type or the wind's speed
The wind direction is measured with wind vanes or wind socks. The wind speed is measured with an anemometer.
Neptune has the fastest wind in the solar system. its speed is 1500 miles per hours (2400 km per hours)
