Gravitational time dilation is a form of time dilation, an actual difference of elapsed time between two events, as measured by observers situated at varying distances from a gravitating mass. The lower the gravitational potential (the closer the clock is to the source of gravitation), the slower time passes, speeding up as the gravitational ...
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
The Gravity Science experiment and instrument set aboard the Juno Jupiter orbiter is designed to monitor Jupiter's gravity. [ 1 ] [ 2 ] [ 3 ] It maps Jupiter's gravitational field , which will allow the interior of Jupiter to be better understood. [ 3 ]
Kepler-1649 contains two Earth-size planets close to a 9:4 resonance (with periods of 19.53527 and 8.689099 days, or a period ratio of 2.24825), including one in the habitable zone. An undetected planet with a 13.0-day period would create a 3:2 resonance chain. [66]
Entering a Hohmann transfer orbit from Earth to Jupiter from low Earth orbit requires a delta-v of 6.3 km/s, [170] which is comparable to the 9.7 km/s delta-v needed to reach low Earth orbit. [171] Gravity assists through planetary flybys can be used to reduce the energy required to reach Jupiter. [172]
An image of Jupiter captured by the Cassini spacecraft on Dec. 7, 2000, as the space probe made its way through the solar system toward Saturn.
A menacing asteroid named Apophis is projected to have a close encounter with Earth in 2029, but scientists have long ruled it out as an impact risk. Asteroids safely fly by Earth all the time ...
Jupiter-mass Binary Objects or JuMBOs are pairs of interstellar planetary-mass objects. They were discovered in the Orion Nebula Cluster by the James Webb Space Telescope . Each component has a mass between 0.7 and 13 Jupiter masses ( M J ), placing them in the planetary-mass regime.
