Why is the Earths orbital velocity is the slowest on July 5 because?

The Earth's orbital velocity is slowest around July 5 due to its position in relation to the Sun during the aphelion, which occurs when the Earth is farthest from the Sun. According to Kepler's laws of planetary motion, a planet moves slower in its orbit when it is farther from the Sun. Consequently, this increased distance results in a decrease in orbital speed, making July 5 the date when the Earth travels at its slowest velocity.
