Physical Laboratory Globe of the Earth
....
Dual purpose lighting, 320mm.
The celestial globe is a model used for navigation, astronomy teaching and the popularization of astronomy auxiliary instrument, it expressed the apparent motion of celestial bodies, coordinate and solve some practical problems by astronomical people.
The celestial sphere is an imaginary sphere introduced into the position and motion of celestial bodies.
The position, star name, constellation, and symbols of several celestial coordinate systems are plotted on the sphere.
According to the selected celestial center is different, a station, and the heliocentric celestial celestial sphere, all celestial bodies on the earth are not the same distance from the observer.

1. The sphere is a circle, the tilt of the earth's axis is 66.5 degrees, and perpendicular to the equatorial plane.
2. The sphere is connected to the support by the earth's axis and can rotate freely and can stop at any position.
3. The products are made up of sphere and bracket.
4. Sphere diameter is 320 ± 5mm, plane scale 1/40000000.
Material: PVC, glossy finish; Approximate thickness 0.19mm; able to survive rough treatment by the children. Inflating valve made of hard plastic, with two plastic loops for inserting rope/thread for hanging.
Topographical globe, inflatable (without the use of a pump): showing continents, oceans, rivers, mountains, deserts, forests, et cetera, but without emphasis on political boundaries (printed in dotted lines).
By making small globe, students are familiar with longitude latitude, equator, north-south regression line, polar circle and international dividing line on globe, and understand geography knowledge: obliquity, day and night cycle, distribution of main mainland and marine on earth.
