* Shape: Elliptical, with a significant eccentricity (0.2056). This means it's quite elongated, with a noticeable difference between its closest and farthest points from the Sun.
* Semi-major axis: 57.91 million kilometers. This is the average distance between Mercury and the Sun.
* Perihelion: 46 million kilometers. This is the point in Mercury's orbit where it's closest to the Sun.
* Aphelion: 69.82 million kilometers. This is the point in Mercury's orbit where it's farthest from the Sun.
* Orbital period: 88 Earth days. This is how long it takes Mercury to complete one full orbit around the Sun.
* Orbital inclination: 7.0 degrees. This is the angle between Mercury's orbital plane and the plane of Earth's orbit (the ecliptic).
* Orbital speed: Mercury's orbital speed varies, being fastest at perihelion and slowest at aphelion. The average orbital speed is approximately 47.87 kilometers per second.
Additional facts:
* Mercury's orbit is slightly tilted compared to the other planets, leading to its unique "resonance" with the Sun. This means that Mercury's rotation period is locked to its orbital period in a 3:2 ratio. This results in Mercury experiencing a "day" that is twice as long as its year.
* Mercury's orbit is also affected by the gravitational pull of the other planets, particularly Jupiter. This causes slight variations in its path over time.
Overall, Mercury's elliptical orbit is a fascinating aspect of this closest planet to the Sun. Its unique characteristics contribute to its extreme temperature variations and other interesting features.
