Read the schematic diagram of the earth's revolution, and complete the requirements: (1) Write the solar terms (that is, two points to two): A is _ _ _ _ _ _ _, and D is _ _ _ _ _. (2) When the earth is fair, (1)A is the vernal equinox, the sun shines directly on the equator, and D is the winter solstice, and the sun shines directly on the tropic of Capricorn.

(4) The movement of the earth around the sun is revolution, and the time of revolution is one year. The astronaut's father is 60 years old.

So the answer is:

(1) vernal equinox; Solstice of winter;
