2. graded adjective. If you describe the appearance of something as fanciful, you mean that it is unusual and elaborate rather than plain and simple. The economic gloom of the early 1980s was relieved by fanciful architecture.
Earth's orbital speed averages about 30 km/s (108,000 km/h; 67,000 mph), which is fast enough to cover the planet's diameter in seven minutes and the distance to the Moon in four hours.
While the Earth orbits around the Sun at a relative 66,700 miles per hour, the Sun is not a stationary object. A widen perspective could include several other facts as well. The earth's rotational speed, depending on how close to the poles varies from 0 to 1040 miles/hour, which at the high end is about .288 miles/sec. This combined with the 66,700 mile/hour mentioned above, is about 18.5 miles/second. It is commonly known that the earth rotates around the sun.
