n.远日点（行星在轨道上距太阳最远之点）

原形：aphelion复数：aphelia

The spacecraft will reach its aphelion, the farthest point from the Sun, in July.
这艘宇宙飞船将于七月到达远日点，这是它离太阳最远的点。
At aphelion, Earth is about 152 million kilometers away from the Sun.
在远日点时，地球距离太阳大约1.52亿公里。
The planet's aphelion occurs once every orbit, marking the time of its greatest distance from the star.
行星的远日点每轨道周期发生一次，标志着它与恒星之间距离最大的时刻。
The difference in temperature between perihelion and aphelion is negligible for Earth.
对于地球来说，近日点和远日点之间的温度差异可以忽略不计。
The comet reaches its aphelion beyond the orbit of Neptune.
这颗彗星的远日点在海王星轨道之外。
Astronomers note that the Earth's position at aphelion has little impact on seasonal temperatures due to the planet's axial tilt.
天文学家指出，由于地球的轴倾斜，远日点对季节性气温的影响很小。
The aphelion of Mars is significantly further from the Sun than its perihelion.
火星的远日点比近日点离太阳远得多。
The spacecraft's communications may experience delays near aphelion due to increased distance from Earth.
随着宇宙飞船接近远日点，由于与地球距离增加，其通信可能会经历延迟。
The study of aphelion and perihelion helps scientists understand orbital mechanics and climate variations.
对远日点和近日点的研究帮助科学家理解轨道力学和气候的变化。
During aphelion, the sunlight received by Earth is about 3.3% less intense than during perihelion.
在远日点，地球接收到的阳光强度比近日点时大约减少3.3%。
