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.
In the case of natural space objects (meteoroids) that orbit around the Sun, these travel at even greater velocities. To remain in its orbit around the Sun, the Earth has to move at 30 km/sec. Other objects that come near the Earth may have relative velocities ranging anywhere from 11 km/sec to 72 km/sec. A 2 mm space debris fragment colliding at 10 km/s is like being hit with a cricket ball at 100 km/hour. 2  A 10 mm fragment at the same speed is like being hit by a large motorbike at 100 km/hour.
