Answer to Question 1

Mercury is airless, but the dense Venusian atmosphere can refract sunlight, creating the bending of light noted in the tear-drop.

Answer to Question 2

Mercury and Venus are both so close to the Sun that it probably tidally locked their equators toward it. Without an axial tilt the angle of the Sun's rays never changes so there are no seasons.
