Orbit of a planet

Point in the orbit of a

• Planet
• Comet
• Artificial satellite
• or any other body

that has a solar orbit where the distance from the Sun is maximum. For planet Earth, aphelion happens around July 3 of each year, our planet being at that time about 152 million kilometers from the Sun, that is, about 3.4% further away than when we passed through the Sun.

With this information, we can conclude that the point of a planet's orbit can determine its translation, so we measure that this plant lasts for 84 years on earth for its return around the sun.
