你是一位物理老师，需要给学生讲解这个题目。单选题答案D，要分析每一个选项，作图时坐标轴原点位置是太阳，行星运行轨迹以太阳原点为中心作图，扫过的面积要以原点为圆心---**Question Stem:** 2. 2023年8月27日发生土星冲日现象，如图所示，土星冲日是指土星、地球和太阳几乎排列成一线，地球位于太阳与土星之间。此时土星被太阳照亮的一面完全朝向地球，所以明亮而易于观察。地球和土星绕太阳公转的方向相同，轨道都近似为圆，地球一年绕太阳一周，土星约29.5年绕太阳一周。则（ ） **Options:** A. 在相同时间内，土星、地球与太阳中心连线扫过的面积相等 B. 土星的运行速度比地球的运行速度大 C. 土星表面重力加速度的数值比地球表面的大 D. 下一次出现土星冲日现象是在2024年 **Image Description:** Type: Diagram illustrating planetary alignment. Title: 土星冲日示意图 (Diagram of Saturn Opposition). Elements: - Sun: Depicted as a large, bright sphere on the right, with rays or glow emanating outwards. Labeled "太阳". - Earth: Depicted as a smaller sphere with continents and clouds, located between the Sun and Saturn. Labeled "地球". - Saturn: Depicted as a sphere with prominent rings, located on the left. Labeled "土星". - Alignment: The Sun, Earth, and Saturn are shown approximately in a straight line, with Earth in the middle. Dashed lines connect the centers of the Sun, Earth, and Saturn, indicating their alignment. - Orbits: Curved lines are shown indicating the orbital paths around the Sun for Earth and Saturn. Earth's orbit is closer to the Sun than Saturn's orbit. Arrows on the curved lines (partially visible) would indicate the direction of revolution, but the diagram doesn't clearly show arrows on the orbits themselves, only on the connecting lines extending outwards from the Earth and Saturn relative to the Sun. The text states the direction of revolution is the same. - Relative Positions: Sun on the right, Earth in the middle, Saturn on the left, aligned approximately horizontally.
