Minutes are a unit of time, not of distance. Perhaps you mean LIGHT minutes, which refer to the distance light travels in a minute. Earth is 1 AU from the sun, which takes light about 8 minutes and 20 seconds. Mars is about 1.5 AU, so when earth and Mars are on the same side of the sun, the distance between them is 0.5 AU. Light would take four minutes, 10 seconds to cross that gap. When Mars and Earth are on opposite sides of the sun, the distance between them is 2.5 AU, which would take light nearly 21 minutes to cross. On average, Earth and Mars would be at roughly right angles to the sun, so you could use the Pythagorean theorem to calculate the distance of their hypotenuse: About 1.8 AU. I'll leave the conversion of this into light time as an exercise for the gentle reader.
It points to the Southern Cross - kind of...
I'm not sure what you mean by "a stable orbit". The Earth's center of mass ... nominally the Earth's center ... always lies in the plane of any Earth orbit, so the ground track of the orbit must either cross the equator or coincide with it.
The star w´ll cross first by about 3 minutes 56 seconds.
If you could cross space directly and ignore Newton's laws like in Star Trek, You would need to cross between 54,710,000 and 401,307,000 kilometers depending on the current orbital/precession status of both planets. However, since current Earth spacecraft burn and coast into an elliptical orbit around the sun such that Mars' gravity will catch the spacecraft; the travel distance to Mars is less than about half of the circumference of Mar's orbit, or about 715 million kilometers, and more than about half of the circumference of the Earth's orbit, or about 470 million kilometers. Differences in designs of spacecraft can change these numbers drastically. Hence it is usually easier to simply refer to the direct line-of-sight distance between the planets.
about 8 and one-third.

The earth rotates 360o of longitude every 24 hours, so it takes 24 ÷ 360 hours to rotate 1o of longitude: 24 ÷ 360 hours = 24/360 hours = 1/15 hours = 1/15 x 60 minutes = 4 minutes The sun will cross 1o of longitude in the same time that the earth takes to rotate 1o of longitude, namely 4 minutes.
A solar eclipse occurs when the moon passes between the Earth and the sun, blocking the sunlight from reaching Earth. The earth and moon must be in positions relative to the sun such that the moon's shadow falls on the earth's surface. The moon's orbit must cross the plane of the ecliptic.
It is a cross section of the Earth. It has no specific name. You can find one at the link below
The astronomical symbol for Earth is a cross surrounded by a circle. The cross probably comes from the Earth being personified as a Goddess, like Mother Earth.
The Sun travels around the Earth once every 24 hours. The Earth is divided into 360 degrees of longitude. Therefore, the Sun transits 15 degrees every hour (360 divided by 24). If it crosses 15 degrees in 60 minutes, it will cross one degree every 4 minutes (60 divided by 15).
There are no planets that cross the earth's orbit. Pluto (dwarf, or minor planet) and Neptune are the only planets whose orbits cross. However there are over 100 asteroids (minor planets) that cross the earth's orbit.
About 3 million
The Equator
The Red Cross has over 100 million volunteers and employees.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
