Mars-crosser asteroid: 4660 Nereus: 1.490: Apollo asteroid, Mars-crosser asteroid: 2003 SQ 222: 1.505 [citation needed] Apollo asteroid, Venus-crosser asteroid, Mars-crosser asteroid. Objects in Mars' zone of influence: Mars: 1.5236: Planet: Objects between Mars' zone of influence and the main asteroid belt: 69230 Hermes: 1.654: Apollo asteroid ...
The temperature of the asteroid belt varies with the distance from the Sun. For dust particles within the belt, typical temperatures range from 200 K (−73 °C) at 2.2 AU down to 165 K (−108 °C) at 3.2 AU. [ 82 ]
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [16] [17] [18] An astronomical unit, or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [19] Small Solar System objects are classified by their orbits: [20] [21]
Mars is located closer to the asteroid belt, ... Mars's average distance from the Sun is roughly 230 million km (143 million mi), and its orbital period is 687 (Earth ...
The close approach to Earth lifted the asteroid's aphelion point (furthest distance from the Sun) from 1.33 AU (inside the orbit of Mars) to 2.06 AU (near the edge of the inner asteroid belt). The approach changed the orbit from an Aten asteroid with a semi-major axis less than 1 AU to an Apollo asteroid with a semi-major axis greater than that ...
Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crossing asteroid. This stony asteroid and relatively fast rotator with a period of 2.27 hours was discovered on 27 June 1949, by German astronomer Walter Baade at the Palomar Observatory in California. [1]
Let the distance from the Sun to Saturn be taken as 100, then Mercury is separated by 4 such parts from the Sun. Venus is 4 + 3 = 7. The Earth 4 + 6 = 10. Mars 4 + 12 = 16. Now comes a gap in this so orderly progression. After Mars there follows a space of 4 + 24 = 28 parts, in which no planet has yet been seen.
Vesta orbits the Sun between Mars and Jupiter, within the asteroid belt, with a period of 3.6 Earth years, [6] specifically in the inner asteroid belt, interior to the Kirkwood gap at 2.50 AU. Its orbit is moderately inclined ( i = 7.1°, compared to 7° for Mercury and 17° for Pluto ) and moderately eccentric ( e = 0.09, about the same as for ...
