How does the moons gravity affect your planet?
The gravity of any body affects all other bodies. In particular the gravity of the Moon creates the tides in bodies of water here on Earth. It also affects our planet's orbit and angle of tilt relative to the plane of its orbit.
What is a stars location determined by?
Astronomers use the coordinate system of RA right ascension also called hour angle, and Declination (Dec)RA is the celestial equivalent of terrestrial longitude. Both RA and longitude measure an east-west angle along the equator; and both measure from a zero point on the equator. For longitude, the zero point is the Prime Meridian; for RA, the zero point is known as the First Point of Aries, which is the place in the sky where the Sun crosses the celestial equator at the March equinox. RA is always zero on the meridian of the celestial sphere which passes through the celestial poles and first point of Aries. Declination is comparable to latitude, projected onto the celestial sphere, and is measured in degrees north and south of thecelestial equator. Therefore, points north of the celestial equator have positive declinations, while those to the south have negative declinations. * An object on the celestial equator has a dec of 0°. * An object at the celestial north pole has a dec of +90°. * An object at the celestial south pole has a dec of −90°.
What is the angle of the celestial north pole above the horizon in Frankfurt Germany?
The altitude of the celestial north pole above the northern horizon is exactlythe observer's north latitude on the earth. The center of Frankfurt is very closeto 50° North latitude.
What is the star latitude and star declination?
Celestial coordinates. -- The star's latitude on the celestial sphere is the same as the Earth latitude that it seems to follow on its way aroujnd the sky. On the celestial sphere, the latitude is called "declination", and is expressed in degrees. -- The star's longitude on the celestial sphere is its angle, measured westward, from the point in the sky called the Vernal Equinox ... the point where the sun appears to cross the celestial equator in March. On the celestial sphere, the star's longitude is called "Right Ascension", and it's expressed in hours. That certainly seems confusing, but an "hour of Right Ascension" just means 15 degrees of celestial longitude. So, as the sky turns, the point directly over your head moves through the stars by 1 hour of Right Ascension every hour.
What angle describe both gibbous phases of waxing and waning?
With the earth at the vertex of the angle, the angle between the sun and moon is between 90 and 180 degrees during the gibbous phases.
What is the name for the relative angle between 2 celestial bodies?
aspect
What do you call the angular relationship between two celestial bodies?
The aspect.Comment: That's a term used in astrology, not in astronomy. I think the correct answer to this question is the astronomical term "position angle".
What invention measured the angle between a celestial body and the horizon?
Sextant
How far from zenith is the celestial equator when it crosses the celestial?
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
What is the function of a sextant?
Sextant is used to measure the angle between any two visible objects.Its primary use is to determine the angle between a celestial object and the the horizon which is also know as objects altitude.
Explain why there is an angle on the ecliptic that is called obliquity on the eclipticwhat is its importance?
it is because the angle between the plane of the earth,s orbit of that of the celestial equator equal to approximately 23"27 minutes at pressent
When was the sextant used?
Sextant, instrument for determining the angle between the horizon and a celestial body such as the Sun, the Moon, or a star, used in celestial navigation to determine latitude and longitude. ... The angular distance of the star above the horizon is then read from the graduated arc of the sextant
What happens when a wave from one medium into another medium at an angle?
as usual.... it gets reflected, absorbed or refracted through a particular angle... the angle being dependent on the relative refractive index between the two mediums.
What is the difference between thread angle and lead angle also clear it from diagram?
A thread angle is the angle of the threads relative to the shank which is 60 degrees for unified screws The lead angle is the pitch of the screw divided by the circumference of the shank; it varies but is around 3 degrees
How does the moons gravity affect your planet?
The gravity of any body affects all other bodies. In particular the gravity of the Moon creates the tides in bodies of water here on Earth. It also affects our planet's orbit and angle of tilt relative to the plane of its orbit.
When a ray passes through two parallel slabs what will be the angle of deviation?
It depends on (a) the angle of incidence, and (b) the relative refractive indices of the slabs as well as the medium on either side of them and between them.
Why is there a twist in a propeller blade?
to keep the angle under which propeller section sees the relative velocity. Because, a propeller essentially is a wing which rotates around an axis parallel to the flight velocity. wings operate best at a certain angle of attack, which is an angle at which wing 'sees' the flow. now, propellers rotate and tangential velocity increases from root to tip. airflow velocity is obviously constant. tangent of angle between relative velocity and prop section is air velocity / tangential velocity. we want angle between propeller section and relative velocity to constant, since tangent changes from root to tip , we need to change angle of propeller section itself.
