  2. Astronomical unit - Wikipedia

    en.wikipedia.org/wiki/Astronomical_unit

    Average distance from the Sun — Earth: 1.00 — Average distance of Earth's orbit from the Sun (sunlight travels for 8 minutes and 19 seconds before reaching Earth) — Mars: 1.52 — Average distance from the Sun — Jupiter: 5.2 — Average distance from the Sun — Light-hour: 7.2 — Distance light travels in one hour — Saturn: 9.5 ...

  3. Saturn - Wikipedia

    en.wikipedia.org/wiki/Saturn

    Animation of Saturn and the Solar System's outer planets orbiting around the Sun Simulated appearance of Saturn as seen from Earth (at opposition) during an orbit of Saturn, 2001–2029. The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU). With an average orbital speed of 9.68 km/s, [6] it takes Saturn 10,759 ...

  4. Cassini–Huygens - Wikipedia

    en.wikipedia.org/wiki/Cassini–Huygens

    Until September 2017 the Cassini probe continued orbiting Saturn at a distance of between 8.2 and 10.2 astronomical units (1.23 × 10 9 and 1.53 × 10 9 km; 760,000,000 and 950,000,000 mi) from the Earth. It took 68 to 84 minutes for radio signals to travel from Earth to the spacecraft, and vice versa. Thus ground controllers could not give ...

  5. List of objects at Lagrange points - Wikipedia

    Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4; like Earth, its mean distance to the Sun is about one astronomical unit. Asteroid (614689) 2020 XL 5 is the second Earth trojan, confirmed in November 2021, oscillating around L 4 in a tadpole orbit and expected to remain there for at least 4000 ...

  6. Rings of Saturn - Wikipedia

    en.wikipedia.org/wiki/Rings_of_Saturn

    The full set of rings, imaged on 19 July 2013 as Saturn eclipses the Sun from the vantage of the Cassini orbiter, 1.2 million kilometres (3 ⁄ 4 million miles) distant. . Earth appears as a dot at 4 o'clock, between the G and E rings – with its brightness artificially exaggerated in this photog

  7. Titius–Bode law - Wikipedia

    en.wikipedia.org/wiki/Titius–Bode_law

    This latter point seems in particular to follow from the astonishing relation which the known six planets observe in their distances from the Sun. 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.

  8. Light-second - Wikipedia

    en.wikipedia.org/wiki/Light-second

    The mean distance, over land, between opposite sides of the Earth is 66.8 light-milliseconds. Communications satellites are typically 1.337 light-milliseconds [citation needed] (low Earth orbit) to 119.4 light-milliseconds (geostationary orbit) from the surface of the Earth. Hence there will always be a delay of at least a quarter of a second ...

  9. Alpha Centauri - Wikipedia

    en.wikipedia.org/wiki/Alpha_Centauri

    Their elliptical orbit is eccentric, so that the distance between A and B varies from 35.6 astronomical units (AU), or about the distance between Pluto and the Sun, to 11.2 AU, or about the distance between Saturn and the Sun. One astronomical unit is the distance from Earth to the Sun, 150 million kilometers.
