Without the Moon the axial tilt of Earth could therefore oscillate chaotically from 0° to 45° on the scale of tens of thousands of years, possibly reaching 85° on timescales of several million years, [11] with severe climatic consequences. [9] [4] [6] More recent studies however suggested that, even without the Moon, Earth's axial tilt could ...
Earthrise, taken on December 24, 1968, by Apollo 8 astronaut William Anders. Earthrise is a photograph of Earth and part of the Moon's surface that was taken from lunar orbit by astronaut William Anders on December 24, 1968, during the Apollo 8 mission.
Apollo 8 (December 21–27, 1968) was the first crewed spacecraft to leave Earth's gravitational sphere of influence, and the first human spaceflight to reach the Moon.The crew orbited the Moon ten times without landing and then returned to Earth.
Made a closest approach of 1,950 kilometres (1,210 mi) on 18 September, and circled the Moon before returning to Earth. Landed in the Indian Ocean on 21 September at 16:08 UTC, becoming the first Lunar spacecraft to be recovered successfully and carried the first Earth life to travel to and around the Moon.

He said that some objects in the belt can come close enough to Earth and at velocities low enough (roughly 2.8 million miles away and 2,200 miles per hour) to allow them to temporarily orbit Earth.
Earthrise (1968). Apollo 8 astronaut Bill Anders recalled, "When I looked up and saw the Earth coming up on this very stark, beat-up Moon horizon, I was immediately almost overcome with the thought, 'Here we came all this way to the Moon, and yet the most significant thing we're seeing is our own home planet, the Earth. ' " [1]
Earth is bidding farewell to a tiny asteroid that joined its orbit for nearly two months. The asteroid, known as 2024 PT5, is set to be drawn away from Earth by the powerful pull of the sun on Monday.
It marked the first time that humans landed on the Moon. Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC , and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC.
