How do you define a celestial body?

A celestial body is any physical body beyond the earth's atmosphere.


How do you determine the altitude at which the celestial equator cuts the meridian?

The altitude at which the celestial equator intersects your local meridian is the complementof your latitude, i.e. the difference between your latitude and 90 degrees.On the equator: Your latitude is zero. (90 - 0) = 90. Celestial equator passes overhead.At the pole: Your latitude is 90. (90 - 90) = 0. Celestial equator coincides with the horizon.In New Orleans, Louisiana, or Durban, South Africa: Your latitude is 30. (90 - 30) = 60.Celestial equator intersects local meridian at 60 degrees above the horizon.

What makes craters on mars?

On every rocky celestial body, a crater is used to define the damage left behind by a meteorite's impact with the ground of the celestial body. Thus, all the craters on Mars are from meteorites that have impacted with Mars's surface. Now you might wonder, "What is a meteorite?" A meteorite is any object in space (asteroid, comet, or meteorite) that has crashed into a celestial body that has a solid surface (i.e., moon, planet, etc...).

How can one derive the escape velocity of an object from a celestial body?

To derive the escape velocity of an object from a celestial body, you can use the formula: escape velocity (2 gravitational constant mass of celestial body / distance from the center of the celestial body). This formula takes into account the gravitational pull of the celestial body and the distance of the object from its center. By calculating this value, you can determine the minimum velocity needed for an object to escape the gravitational pull of the celestial body.


In the horizon coordinate system altitude-azimuth how many degrees does a star at the celestial equator move in 1 hour and how many arcseconds does the star move in 1 second of time?

A star at the celestial equator will move 15 degrees in altitude per hour, and 15 arcseconds in 1 second of time. This is because the celestial equator intersects the celestial sphere at 90 degrees from the north and south celestial poles, so the stars appear to move in circles around the celestial poles.
