Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...
Moving far backwards in time, more than 200,000 years ago Venus sometimes passed by at a distance from Earth of barely less than 38 million km, and will next do that after more than 400,000 years. Venus and Earth come the closest, but they come less often closer than Venus and Mercury. [10]
When Venus lies between Earth and the Sun in inferior conjunction, it makes the closest approach to Earth of any planet at an average distance of 41 million km (25 million mi). [ 4 ] [ note 3 ] [ 172 ] Because of the decreasing eccentricity of Earth's orbit , the minimum distances will become greater over tens of thousands of years.
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. [291] Uranus, having occasionally been observed since 1690 and possibly from antiquity, was recognized to be a planet orbiting beyond Saturn by 1783. [292]
The distance at close approach varies between about 54 and 103 million km (34 and 64 million mi) due to the planets' elliptical orbits, which causes comparable variation in angular size. [190] At their furthest Mars and Earth can be as far as 401 million km (249 million mi) apart. [191] Mars comes into opposition from Earth every 2.1 years.
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
Venus in Pisces Trine Mars Retrograde in Cancer Stirs Up Romantic Feelings — and Drama — for These 3 Zodiac Signs. Valerie Mesa. January 24, 2025 at 10:33 AM.
The first two objects that were detected and had their Earth-MOID calculated before Earth impact were the small asteroids 2008 TC 3 and 2014 AA. 2014 AA is listed with a MOID of 0.00000045 AU (67 km; 42 mi), [5] and is the second smallest MOID calculated for an Apollo asteroid after 2020 QY 2 with an Earth-MOID of 0.00000039 AU (58 km; 36 mi).
