How Far is Mars from the Sun?
Mars' Orbital Distance from the Sun
Mars, the fourth planet in our Solar System, orbits the Sun at an average distance of approximately 227.9 million kilometers (141.6 million miles)2 5 6. This distance is not constant due to the elliptical nature of Mars' orbit. The planet's distance from the Sun varies between 207 million kilometers (128.6 million miles) at its closest approach, known as perihelion, and 249 million kilometers (154.7 million miles) at its farthest point, known as aphelion3.
Mars' Orbital Characteristics
Mars' orbit around the Sun is more eccentric compared to Earth's nearly circular orbit. This eccentricity results in significant variations in its distance from the Sun throughout its orbital period of 687 Earth days2 3. The elliptical orbit of Mars was first accurately described by Johannes Kepler in the early 17th century, who noted that the Sun occupies one of the foci of the ellipse3.
Historical Context and Observations
The understanding of Mars' distance from the Sun has evolved significantly over time. Early observations by astronomers like Tycho Brahe and Johannes Kepler laid the groundwork for our current knowledge. Kepler's laws of planetary motion, derived from meticulous observations of Mars, were pivotal in establishing that planets move in elliptical orbits3.
Mars' Position Relative to Earth
Mars' proximity to Earth varies greatly due to the differing orbital periods of the two planets. For instance, in early November, Mars was approximately 45 million miles away from Earth, a distance that will not be matched for another 17 years1. During opposition, when Mars and the Sun are on directly opposite sides of Earth, the distance can be as short as 36 million miles4.
Conclusion
Mars orbits the Sun at an average distance of 227.9 million kilometers, with significant variations due to its elliptical orbit. Historical observations and modern measurements have provided a detailed understanding of Mars' position and movement within our Solar System. This knowledge not only enhances our comprehension of Mars but also enriches our broader understanding of planetary dynamics.

Star tracker to be used in study of Mars
IN EARLY NOVEMBER, Mars was approximately 45 million miles away from Earth. At that time, it was closer to Earth than it will be again for the next 17 years. Seventh in size, Mars is the fourth closest planet to the sun. Earth, fourth largest of the planets, is third from the sun. Mars is 4,399 miles in diameter, Earth 7,918 miles in diameter.
The Sun Data shows Relativistic Effects (revised)
Mars had to migrate from its original orbital distance of 84 million km to 227.9 million km due to relativistic effects.
PreprintThe Giant-Impact Hypothesis Supports "Mars Immigration Theory" (Iii)
Mars Immigration Theory (Iii) supports the idea that Mars had a giant-impact event that caused collisions with Venus and Earth, leading to the formation of moons and the formation of Jupiter's rings and Asteroid belt.
PreprintDoes Mars Fit his Position Is The Solar Group? Why Not?!
Mars data no longer fits its new position in the solar group, as it has immigrated from its original position with distance 84 million km to 227.9 million km.
