One galactic year is approximately 225 million Earth years. [2] The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its trajectory around the Galactic Center, [ 3 ] a speed at which an object could circumnavigate the Earth's equator in 2 minutes and 54 seconds; that speed corresponds to ...
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 Earth days (or about 29 + 1 ⁄ 2 years) [86] to finish one revolution around the Sun. [6] As a consequence, it forms a near 5:2 mean-motion resonance with Jupiter. [87]
Earth's surface temperature will reach around 420 K (147 °C; 296 °F), even at the poles. [82] [98] 2.8 billion High estimate until all remaining Earth life goes extinct. [82] [98] 3–4 billion The Earth's core freezes if the inner core continues to grow in size, based on its current growth rate of 1 mm (0.039 in) in diameter per year.
Earth eccentricity is very low (0.0167 in a scale from 0 to 1.0000), hence it does not affect so much temperature changes during the year. Year duration [ edit ]
The most distant space probe, Voyager 1, was about 18 light-hours (130 au,19.4 billion km, 12.1 billion mi) away from the Earth as of October 2014. [29] It will take about 17 500 years to reach one light-year at its current speed of about 17 km/s (38 000 mph, 61 200 km/h) relative to the Sun.
Saturn has been bringing life lessons around wealth, possessions and values, Aquarius. This can be tied to "self-worth and self-love" for the next three years, says Thomas.
Earth may have had a ring made up of a broken asteroid over 400 million years ago, a study finds. The Saturn-like feature could explain a climate shift at the time.
Distance of the outer limit of Oort cloud from the Sun (estimated, corresponds to 1.2 light-years) — Parsec: 206 265 — One parsec. The parsec is defined in terms of the astronomical unit, is used to measure distances beyond the scope of the Solar System and is about 3.26 light-years: 1 pc = 1 au/tan(1″) [60] [61] Proxima Centauri: 268 000 ...
