3 dni temu · Venus orbits the Sun at a mean distance of 108 million km (67 million miles), which is about 0.7 times Earth’s distance from the Sun. It has the least eccentric orbit of any planet, with a deviation from a perfect circle of only about 1 part in 150.

1 dzień temu · 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.
2 dni temu · The easiest way to determine stellar distance to the Sun for objects at these distances is parallax, which measures how much stars appear to move against background objects over the course of Earth's orbit around the Sun.
3 dni temu · The clouds that enshroud Venus are enormously thick. The main cloud deck rises from about 48 km (30 miles) in altitude to 68 km (42 miles). In addition, thin hazes exist above and below the main clouds, extending as low as 32 km (20 miles) and as high as 90 km (56 miles) above the surface.
4 dni temu · The Earth takes 365 days (i.e. one year) to orbit the Sun while Venus takes 225 days. The combination of these two orbital periods leads to the Earth-Venus-Sun forming a straight line roughly every 584 days.
3 dni temu · Important early telescopic observations of Venus were conducted in the 1700s during the planet’s solar transits ( see eclipse: Transits of Mercury and Venus ). In a solar transit an object passes directly between the Sun and Earth and is silhouetted briefly against the Sun’s disk.
3 dni temu · Mercury has the most eccentric orbit of all the planets in the Solar System; its eccentricity is 0.21 with its distance from the Sun ranging from 46,000,000 to 70,000,000 km (29,000,000 to 43,000,000 mi). It takes 87.969 Earth days to complete an orbit.
