Jupiter does not have a solid surface, and the lowest atmospheric layer, the troposphere, smoothly transitions into the planet's fluid interior. [2] This is a result of having temperatures and the pressures well above those of the critical points for hydrogen and helium, meaning that there is no sharp boundary between gas and liquid phases.
Jupiter has been visited by automated spacecraft since 1973, when the space probe Pioneer 10 passed close enough to Jupiter to send back revelations about its properties and phenomena. [168] [169] Missions to Jupiter are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v.
G is the universal gravitational constant (G ≈ 6.67 × 10 −11 m 3 ⋅kg −1 ⋅s −2 [4]) g = GM / d 2 is the local gravitational acceleration (or the surface gravity , when d = r ). The value GM is called the standard gravitational parameter , or μ , and is often known more accurately than either G or M separately.
In science class, we always learned that all the planets in our solar system orbit around the sun. Scientists have figured out this is not necessarily true.
For these reasons Jupiter has the highest frequency of impacts of any planet in the Solar System, justifying its reputation as the "sweeper" or "cosmic vacuum cleaner" of the Solar System. [7] 2018 studies estimate that between 10 and 65 impacts per year of meteoroids with a diameter of between 5 and 20 meters (16 and 66 ft) can occur on the ...
Formally, c is a conversion factor for changing the unit of time to the unit of space. [4] This makes it the only speed which does not depend either on the motion of an observer or a source of light and / or gravity. Thus, the speed of "light" is also the speed of gravitational waves, and further the speed of any massless particle.
Images taken of Jupiter by NASA's James Webb Space Telescope show a roaring jet stream over the gas giant's equator that is moving at speeds twice as fast as the winds of a Category 5 hurricane ...
A fast radio burst, ... Further observations allowed the team of astronomers to trace FRB 20240209A to a region of space associated with an 11.3-billion-year-old galaxy that no longer forms stars ...
