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.
The earth's orbit around the sun is elliptical, so the earth moves at a constantly varying velocity as it moves closer to the sun (perihelion) or further away (aphelion). The earth's angular velocity (speed of movement) is considerably greater at perihelion than it is at aphelion.he earth gets through 10% of its path in the same length of time whether it is at aphelion (moving slowly) or perihelion (moving fast). The absolute speed at which the earth moves varies, but the rate at which it orbits is constant.
