    Venus is the second planet from the Sun, making a full orbit in about 224 days. Venus orbits the Sun at an average distance of about 0.72 AU (108 million km; 67 million mi), and completes an orbit every 224.7 days. It completes 13 orbits in 7.998 years, so its position in our sky almost repeats every eight years.

  3. Orbit of Venus - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Venus

    [1] [2] The low eccentricity and comparatively small size of its orbit give Venus the least range in distance between perihelion and aphelion of the planets: 1.46 million km. The planet orbits the Sun once every 225 days [ 3 ] and travels 4.54 au (679,000,000 km; 422,000,000 mi) in doing so, [ 4 ] giving an average orbital speed of 35 km/s ...

    Careful observations of the 1769 transit of Venus allowed astronomers to calculate the average Earth–Sun distance as 93,726,900 miles (150,838,800 km), only 0.8% greater than the modern value. [293] Uranus, having occasionally been observed since 1690 and possibly from antiquity, was recognized to be a planet orbiting beyond Saturn by 1783. [294]

    At that close distance, "Parker will cut through plumes of plasma still connected to the Sun," NASA says, adding that the probe will be "close enough to pass inside a solar eruption, like a surfer ...

    After waiting for most of the day, he eventually saw the transit when clouds obscuring the Sun cleared at about 15:15, half an hour before sunset. His observations allowed him to make a well-informed guess for the diameter of Venus and an estimate of the mean distance between the Earth and the Sun (59.4 million mi (95.6 million km; 0.639 AU)).

    Within two months of launching, the Parker Solar Probe in October 2018 moved within 26.55 million miles of the sun's surface, breaking the previous mark set by the Helios-2 spaecraft in 1976.

    Comet G3 ATLAS (C/2024) is expected to make its return for a close encounter with the Sun in mid-January, giving skywatchers the chance to spot one of the brightest comets in 20 years from Earth.

    It used repeated gravity assists from Venus to develop an eccentric orbit, approaching within 9.86 solar radii (6.9 million km or 4.3 million miles) [7] [8] from the center of the Sun. At its closest approach in 2024, its speed relative to the Sun was 690,000 km/h (430,000 mph) or 191 km/s (118.7 mi/s), which is 0.064% the speed of light .
