The solar typically rises within the - ANSEast
A reporter at the newspaper says that she saw a full moon last night time. The statement is
most in all likelihood... - ANSAn commentary of the natural world
The commentary that there are constellations that can be seen from Egypt but now not from
Greece satisfied the historical greeks that, - ANSThe Earth is round
An place of the sky this is marked by means of a recognizable sample of stars is referred to
as - ANSA constellation
The stars, as seen from the Earth, appear like attached to - ANSThe celestial sphere, a
sphere that surrounds the Earth
Who located the Geocentric version? - ANSPtolemy
Who observed the Heliocentric model for the first time in history? - ANSAristarchus
Eratosthenes of Cyrene is usually credited with using the angle of the midday sun at
Alexandria and Syene to determine the - ANSSize of the Earth
Where are the stars all through the day? - ANSThe Sun is too vivid compared to distant
stars. If we block Sun light, then we will see the celebs
The time it takes for Earth to rotate on its axis so that distant stars appear in the identical
function within the sky is known as the - ANSSidereal day
Model that represents the Sun in the middle and planets rotate round it - ANSHeliocentric
model
Model that represents the Earth inside the center and planets rotate round it -
ANSGeocentric model
The planets pass frequently eastward relative to the remote stars but as soon as at some
point of every experience around the Celestial Sphere, they loop again westward for a while.
This motion is called - ANSRetrograde motion
In addition to measuring the position of all of the planets on the time, Tycho Brahe measured
them to an accuracy of - ANS1/60 diploma of arc
A superstar that is named Alpha Eridani is maximum likely - ANSThe brightest star in the
constellation Eridanus
, A megastar that is known as Delta Cepheus is maximum probably - ANSA fairly dim
megastar within the constellation Cepheus
A time of 24 hours is - ANSExactly same to a solar day
What causes Earth's seasons? - ANS23.5 degree tilt of Earth's rotational axis
If you were standing at the Earth's North Pole, in which might you notice the north celestial
pole (Polar Star, Polaris)? - ANSOverhead (zenith)
Some constellation located within the summer skies are distinct from those determined in the
winter skies. The high-quality explanation for this statement is that - ANSThe Earth revolves
around the Sun
Kepler found that the orbit of planets is quality described as - ANSAn ellipse with the Sun at
one focus
Stellar parallax is resulting from - ANSThe revolution of the Earth around the Sun
The arcminute is a size of a(n) ___ in astronomy - ANSAngle
Suppose an asteroid has a semimajor axis of 4 AU. How long does it take the asteroid to
move across the Sun? - ANS8 years
The big name Proxima Centauri shows a stellar parallax attitude of 0.722 arcsec while the
brightest megastar Vega has a parallax of zero.129 seconds of arc. From this you can finish
that - ANSProxima Centauri is towards our Sun than Vega
What is the direction that the Sun, Moon, and planets observe through the constellations? -
ANSThe ecliptic
In at some point, the location of the solar at the Celestial Sphere - ANSMoves eastward
along the ecliptic by using 1
The megastar Sirius may be positioned by the use of the pointer stars in - ANSOrion
The earliest known measurement of circumference of the Earth used - ANSNoon Sun angles
at places to decide the attitude among the Earth radii to those places
The route of the Sun at the Celestial Sphere is referred to as - ANSThe ecliptic
How long does it take the Sun to complete one circuit of ecliptics? - ANS1 yr
Stars in the constellation are - ANSIn the same a part of the sky
The angle of parallax increases as - ANSThe baseline receives smaller or distances to stars
decrease
