It is false, due to precession of the equinoxes, but true enough to apply to short-term analysis.
orbit of the moon
1. Tilt of earths axis 2. Earths axis remains parallel throughout its yearly orbit.
The axis of Earth remains relatively fixed in space, pointing in the same direction in relation to the stars. It does not alter its parallel orientation. However, Earth's axial tilt does change slightly over long periods due to gravitational interactions with other celestial bodies.
In geography, "parallel" usually refers to lines of latitude that run parallel to the equator. These lines help in locating places on Earth's surface in relation to the equator. They are used to measure distances north or south of the equator.
No; it's about 23 degrees off the plane of its orbit.
The earths rotation about its axis has no affect on the orbit of satellites about earth. Only their relative velocities and positions are relevant, not their orientation
Its the orientation of the earths rotational axis that defines the equinox, the axis remains parallel throughout the orbit of the sun, and when its side on to the sun (spring and autumn), thats the equinox (equal length of day and night).
because of the earths axis
The earths rotational axis is tilted approx. 23 degrees from vertical The earths rotational axis remains parallel throughout its rotation around the sun, high summer (longest day) in the northern hemisphere, is when the top of the axis is at full tilt toward the sun. (shortest day in the southern hemisphere)
intersect
During a solstice, either the summer or winter solstice, Earth's axial tilt causes one hemisphere to be tilted towards the Sun, resulting in longer or shorter days depending on the hemisphere. This is when the Sun reaches its highest or lowest point in the sky, leading to the longest day or night of the year.
y=-2.5 is parallel to the x axis. The equation of the x axis is y=0
