Every minute more corresponds to ca. Io was originally named Jupiter I being the closest to the planet. The semi-major axis is the mean value of the smallest and largest distances from one focus to the points on the ellipse. [6], This article is about the asteroid. $, is $ a^{-1}\,\!

The largest moon in the solar system is Ganymede.

With a two-digit number and a two-letter name, 85 Io has the shortest designation of all minor planets. The is the average distance in km of the object is from its parent 421800.00. It was discovered in the year 1610 by Galileo Galilei.

It is related to the semi-minor axis $ b\,\! A name is preferred even if its a random made up one by yourself.

$ faster than $ b\,\! The Moon's average barycentric orbital speed is 1.010 km/s, whilst the Earth's is 0.012 km/s.

Its mass is estimated/calculated at being 89,319,379,731,108,900,000,000 kg. Tidal Lock: Over 1.8 Earth days, Io rotates once on its axis and completes one orbit of Jupiter, causing the same side of Io to always face Jupiter.

In geometry, the term semi-major axis (also semimajor axis) is used to describe the dimensions of ellipses and hyperbolae.

Hi there! The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 421.8, which is the furthest point from the centre to the edge of an elliptical point. [3] This gives an axial tilt of about 125° or 115°, respectively.

Its volume is 25319064907. The semi-major axis of a hyperbola is one half of the distance between the two branches; if this is a in the x-direction the equation is: $ \frac{\left( x-h \right)^2}{a^2} - \frac{\left( y-k \right)^2}{b^2} = 1 $, In terms of the semi-latus rectum and the eccentricity we have. $ tend to infinity, $ a\,\!

$ and $ r={\ell\over{1-e}}\,\! $ \mu = GM \, $ (standard gravitational parameter). The plumes have been viewed with large telescopes from Earth. Io (minor planet designation: 85 Io is carbonaceous asteroid from the central region of the asteroid belt, approximately 170 kilometers in diameter.

Remarkably, the orbiting body's path around the barycentre and its path relative to its primary are both ellipses. Solar System Dynamics. The orbital eccentricity is 0.0041, it is the degree at which Io orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

The mass ratio in this case is 81.30059. As a cow, Hera took interest in the cow and demanded that she should have it. Like 141 Lumen it is an interloper that orbits within the Eunomia asteroid family but it is not related to the shattered parent body.

Take your favorite fandoms with you and never miss a beat. There are 233 semimajor axis-related words in total, with the top 5 most semantically related being ellipse, eccentricity, hyperbola, geometry and focus.You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. Its density has been calculated at being 3.528.

$.

Below is a massive list of semimajor axis words - that is, words related to semimajor axis. Io is a retrograde rotator, with its pole pointing towards one of ecliptic coordinates (β, λ) = (-45°, 105°) or (-15°, 295°) with a 10° uncertainty. Some of the volcanoes and mountains are higher than Everest which is the highest mountain on our planet, the Earth. Thus $ a\,\! In geometry, the term semi-major axis (also semimajor axis) is used to describe the dimensions of ellipses and hyperbolae.

You can decline to give a name which if that is the case, the comment will be attributed to a random star. The planet has over 400 active volcanoes. The value is the radius in km of the said object at the Equator. It is the closest to the planet of all the Galilean moons with Callisto being the furthest. It is often said that the semi-major axis is the "average" distance between the primary (the focus of the ellipse) and the orbiting body. If the white lines are below, the path is above the ecliptic.

$, as follows: A parabola can be obtained as the limit of a sequence of ellipses where one focus is kept fixed as the other is allowed to move arbitrarily far away in one direction, keeping $ \ell\,\! $ and $ b\,\! Its shape is quite regular.

The atmospheric gases within the atmosphere of the object are Sulfur dioxide. Io is also the name of the volcanic satellite of Jupiter. In astrodynamics the orbital period $ T\, $ of a small body orbiting a central body in a circular or elliptical orbit is: Note that for all ellipses with a given semi-major axis, the orbital period is the same, regardless of eccentricity.

This form turns out to be a simplification of the general form for the two-body problem, as determined by Newton: where G is the gravitational constant, and M is the mass of the central body, and m is the mass of the orbiting body. The mean value of $ r={\ell\over{1+e}}\,\! Energy; calculation of semi-major axis from state vectors, $ \epsilon = { v^2 \over {2} } - {\mu \over \left | \mathbf{r} \right |} $. Io appeared as a character in the re-imagined version Clash of the Titans (2010) played by Gemma Arterton. Io receives more than 1000 x the amount of radiation that is needed to kill a person. The moon is only slightly larger than our Moon and is the fourth largest moon in the Solar system. (magnitude 13.8). The semi-major axis is one half of the major axis, and thus runs from the centre, through a focus, and to the edge of the ellipse. The surface area of Io is 41,698,064.74. The cow was placed up under lock and key with a 100 eyed monster guarding it. 4 Eruptive The moon Io is the most volcanically active world in the solar system.

$. The difference between the primocentric and "absolute" orbits may best be illustrated by looking at the Earth-Moon system.

It is an identified Eunomian interloper. The equatorial circumference of Io is 11445.5 km.

The moon is tidally locked to the planet, only ever showing one side of its face to the planet at anyone time. It is one of the most geologically active moons of any planet in the system owing in part to its location being closest. The chances of finding life on the surface would next to zero. The character was inserted to increase the number of female characters and does not figure in the original Grecian legend. for a given central body and semi-major axis, the total specific energy is always the same. The International Space Station has an orbital period of 91.74 minutes, hence the semi-major axis is 6738 km [1]. The Escape Velocity of the object is 8,552 km/h. The larger an object is, the more velocity (speed) is needed to break free from the object.The Semi-Major Axis of the orbit is 421.8, which is the furthest point from the centre to the edge of an elliptical point.

The orbital period, i.e. The surface gravity of the said item is 1.796. Io is a retrograde rotator, with its pole pointing towards one of ecliptic coordinates (β, λ) = (-45°, 105°) or (-15°, 295°) with a 10° uncertainty.

Making that assumption and using typical astronomy units results in the simpler form Kepler discovered. The Mean orbit velocity, that is the speed at which it orbits is 62423.10 km/h.

50 km more: the extra 300 km of orbit length takes 40 seconds, the lower speed accounts for an additional 20 seconds. If the white lines are above, then the path of the object is under the ecliptic. [4] Another asteroid occultation of Io (magnitude 13.2) occurred on March 12, 2009, from the eastern United States, with the star 2UCAC 35694429 This is not quite accurate, as it depends over what the average is taken.

The barycentric lunar orbit, on the other hand, has a semi-major axis of 379,700 km, the Earth's counter-orbit taking up the difference, 4,700 km. It was not until after the death of Galileo that the name changed to the more familiar Io that we know today.
