To determine which planet is closest to the Sun based on their orbital periods, we can use Kepler's Third Law, which states that the square of a planet's orbital period is proportional to the cube of its average distance from the Sun. Generally, planets with shorter orbital periods are closer to the Sun. Without the specific values from the table, we cannot identify which planet (A, B, C, or D) is closest, but the one with the shortest orbital period would be the closest to the Sun.
The planets closest to the sun are Mercury, Venus, Earth, and Mars. These planets are small and rocky, with solid surfaces, and they are known as the terrestrial planets. They have shorter orbital periods and higher average densities compared to the outer gas giants.
The point when an orbiting object is closest to the central object is called periapsis. For the specific case of planets around the Sun, the term perihelion is used as well.
The inner planets
All planets in our solar system will never align perfectly in a straight line due to their different orbital paths and speeds. The closest alignment that occurs is called planetary alignment, and it happens roughly every 500 years.
The inner planets are called "rocky" or terrestrial, a name which underscores the contrast with the outer gas giant planets.

The inner planets
The four planets closest to the sun are called the inner planets. They are Mercury, Venus, Earth, and Mars. The asteroid belt lies between the inner and outer planets.
Perihelion
The inner planets, also known as terrestrial planets (Mercury, Venus, Earth, Mars), are smaller, rockier, and have solid surfaces. The outer planets, also called gas giants (Jupiter, Saturn, Uranus, Neptune), are larger, primarily made of gas, and have no solid surface. Both sets of planets orbit the Sun, but inner planets are closer to the Sun and have shorter orbital periods, while outer planets are farther away and have longer orbital periods.
Venus and Earth. They are often called brother planets.
The first four planets closest to the Sun are the four terrestial planets.
"The Inner Planets" is the common term for the four planets closest to our sun.
Mercury, Venus, Earth, and Mars are the four planets closest to the sun and are referred to as the inner planets in our solar system.
