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.
velocity=107,300 km/h (or if you prefer 67,062 miles per hour). So the Earth moves at about 100,000 km/h around the Sun (which is 1000 times faster than the speeds we go at on a highway!). Thanks for your explanation, but I was hoping for an explanation a little more precise, since I already knew the one you gave.
