    circumference of the real Earth is close to 40 million metres. Celestial globes show the apparent positions of the stars in the sky. They omit the Sun‚ Moon and planets because the positions of these bodies vary relative to those of the stars‚ but the ecliptic‚ along which the Sun moves‚ is indicated. Globes are round maps of the earth that are designed with vertical and horizontal lines. These imaginary lines‚ including the equator and the prime meridian aid in finding any location on the globe.

    eclipse can occur at least two and no more than five times a year. Unlike Solar eclipses‚ lunar eclipses can only occur during a full moon and when the moon is on the ecliptic plane. Only during full moon‚ the Sun’s light will be blocked. Solar eclipses can only occur during a new moon and when the moon is on the ecliptic plane. This is the time when the moon’s shadow casts on the Earth. The total phase of a lunar eclipse can last for 90 minutes or more. The maximum time a lunar eclipse can

    the Earth‚ and in the same orbital plane‚ there would be total solar eclipses every single month. However‚ the Moon’s orbit is inclined (tilted) at more than 5 degrees to Earth’s orbit around the Sun (see ecliptic) so its shadow at new moon usually misses Earth. Earth’s orbit is called the ecliptic plane as the Moon’s orbit must cross this plane in order for an eclipse (both solar as well as lunar) to occur. In addition‚ the Moon’s actual orbit is elliptical‚ often taking it far enough away from Earth
