What is the foci of an eclipse?
The foci of an eclipse is 2.
What causes a solar eclipse to be annular?
The Moon's distance from the Earth can vary. This is because the Moon orbits the Earth in an ellipsoid manner, with the Earth at one of the foci. On this ellipsoid the Moon can be nearer to, or further away from the Earth. When all objects are further away from the observer, they appear to be smaller. Hence fir an annular eclipse the Moon is further away, therefore it appears smaller and allows a 'ring' of solar light around the black lunar disc. When the Moon is nearer the Earth you have a Total Solar Eclipse, where at best you only see the corona. NB the word 'foci' is the plural of the noun 'focus'. 'Focuses' is the verb. An ellipse has two foci. The Earth being at one of the foci, the other being a 'blind' foci. The word 'foci' is pronounced as 'foe-s-eye'. the 'c' is soft and pronounced like an 's'.
What is foci and why are they important?
By definition, foci are the centres of interest or activity and so are important.
The sun is located in an elliptical galaxy?
Sun is important to earth cause it produces light needed for plants(photosynthese) to make O2(oxygen)Without the suns heat and light we could not surviveIf there is no sun then there would be no life on Earth. All the plants would die, then all the animals that eat plants would die then humans who eat both the plants and animals would die. Not to mention it would become very, very cold.
What is the sun and how does it relate to other objects in the solar system?
The sun is a star.It's the only self-luminous body in the solar system.The gravitational force of mutual attraction between the sun and everything in a closed orbitaround it is what makes the closed orbits possible.One focus of the elliptical path of everything in closed orbit around the sun is at the center of the sun.The orbits of the planets are so nearly circular (small eccentricity) that the center, as well as both foci,of every planetary orbit is inside the sun. This isn't true of most repeating cometary orbits.
Which object is located at one foci of the elliptical orbit of Mars?
probably the sun since one of earths eliptical foci is the sun
Is the sun the center of your solar system true or false?
TRUE!!!! All the planets in the Solar system including Earth orbit the Sun, in ellipses. The Sun lies at one of the foci of these ellipses, NOT the centre. So the Sun is NOT at the 'dead' centre of the Solar system.
What are the comets that go through the solar system?
All visible comets go through the solar system. Those that return periodically have elliptical orbits with the sun as one of the foci. Those that do not usually have hyperbolic orbits with the sun as a focus.
Can the foci of an ellipse can be outside the ellipse?
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
Can the foci of an ellipse be outside of the ellipse?
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
CanThe foci of an ellipse can be outside the ellipse?
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.
Is the foci of an ellipse always lie inside the ellipse?
Yes.
What do the planets of our solar system orbit?
All of the planets (major, dwarf, and minor) as well as all other objects in our solar system orbit the sun.Technically each object is orbiting a point between the center of the object and the center of the Sun called "The Center of Gravity," but this point is deep inside the Sun so it is safe to say that the objects orbit the sun without causing too much error.
What object is located at the foci of Jupiter's orbit?
Objects such as planets move around the Sun in ellipses; the Sun is at ONE of the foci of the ellipse. The other focus has no special significance in astronomy.
The foci of an ellipse will always lie inside the ellipse?
true
What is the shape of the ellipse that both foci in the same place?
Both foci of any ellipse are always in the same plane.If they're both at the same point, then the ellipse is a circle.
What happens when you increase the distance between two foci?
-- If they're the foci of a single optical system, then the result can't be stated in general.It depends on the curvatures and relative position of the lenses.-- If they're both the foci of the same ellipse, then the ellipse becomes more eccentric.That is, more squashed and less circular.-- If they're the foci of two parabolas, then there's no relationship between them, andnothing in particular depends on the distance between them.The answer depends on whether they are the foci of an ellipse or a hyperbola.
