There are no rearward loops in the Moon's solar orbit. Considering the Earth–Moon system as a binary planet, its centre of gravity is within Earth, about 4,671 km (2,902 miles) [24] or 73.3% of the Earth's radius from the centre of the Earth. This centre of gravity remains on the line between the centres of the Earth and Moon as the Earth ...
The semi-major axis of the geocentric lunar orbit, called the lunar distance, is approximately 400,000 km (250,000 miles or 1.28 light-seconds), comparable to going around Earth 9.5 times. [178] The Moon makes a complete orbit around Earth with respect to the fixed stars, its sidereal period, about once every 27.3 days.
Cernan's last words from the lunar surface, along with Lunar Module Pilot Harrison Schmitt's recollections, were used by the band Public Service Broadcasting for the song "Tomorrow", the final track of their 2015 album The Race for Space. [50] The Apple TV+ show For All Mankind dramatizes the Moon landings. The fictional main character draws ...
Called a "mini-moon" of sorts by some, it temporarily entered Earth's orbit on Sept. 29 from the Arjuna asteroid belt, which follows a similar orbital path around the sun as the Earth.
Most lunar low orbits below 100 km (60 mi) are unstable. [2]Lunar Module Eagle in lunar orbit during Apollo 11, July 1969. Gravitational anomalies slightly distorting the orbits of some Lunar Orbiters led to the discovery of mass concentrations (dubbed mascons) beneath the lunar surface caused by large impacting bodies at some remote time in the past.
Earth-Moon Lagrangian points: a spacecraft in an NRHO around the L2 Lagrange point would have a view of Earth unobstructed by the Moon. A halo orbit is a periodic, three-dimensional orbit associated with one of the L 1, L 2 and L 3 Lagrange points. Near-rectilinear means that some segments of the orbit have a greater curvature than those of an ...
The orbit of a satellite of Earth fundamentally depends on the gravity of the Earth–Moon system, whereas the orbit of a co-orbiting object would negligibly change if Earth and the Moon were suddenly removed because a quasi-satellite is orbiting the Sun on an Earth-like orbit in the vicinity of Earth.

NASA astronaut Catherine Coleman plays a flute aboard the International Space Station in 2011.. Music in space is music played in or broadcast from a spacecraft in outer space. [1] [failed verification] The first ever song that was performed in space was a Ukrainian song “Watching the sky...” [2] (“Дивлюсь я на небо”) sung on 12 August 1962 by Pavlo Popovych, cosmonaut ...
