Answers
Answer:
1. The Milky Way Galaxy
2. The event known as equinox is eagerly awaited by space enthusiasts as it takes place twice a year on March 21 and September 23. Days and nights are equal at all places on earth on March 21 because on this day sun rays will fall in the vertical direction towards the equator or at the center position of the earth.
3. Hot- Torrid Zone
Cold- Frigid Zone
4. The circle of illumination is the division between day and night over the earth. The circle of illumination bisects (cuts in half) all latitudes on the spring and autumnal equinoxes. At this time, all places have equal day length (12 hours). The circle of illumination always bisects the equator (0 degrees latitude).
5. It also leaves the lunar surface exposed to half as much radiation as in interplanetary space (with the other half blocked by the Moon itself underneath the colony), raising the issues of the health threat from cosmic rays and the risk of proton exposure from the solar wind.
Answer: 1 . Our planet belongs to milky way galaxy.
