Venus' size and distance was first determined, and from that point, scientists tracked the travel of Venus across the "face of the sun" with one group set up in the northern hemisphere and one group in the Southern Hemisphere. In this manner, they used the science of optics to determine the size of the sun.

How big would the sun be if it was a black hole?
Firstly our sun is too small to become a black hole. Only stars that are a million to a billion times our sun do this, because they burn through their fuel quickly, unlike our sun. A typical black hole has 3 times the mass of our sun
Does the size of a planet affect the time it takes for one revolution around the sun?
The size of a planet does not directly affect the time it takes for it to complete one revolution around the sun, which is determined by its distance from the sun and the gravitational forces at play. According to Kepler's laws of planetary motion, a planet's orbital period is related to the semi-major axis of its orbit, not its size. Therefore, two planets of different sizes but at the same distance from the sun will have similar orbital periods.
If the mass of the Sun decreases because of nuclear fusion why don't we see the Sun decreasing in size?
The amount of mass lost through nuclear fusion is only 7/10 of 1% of the mass of the four hydrogen nuclei. However, it takes a multitude of reactions for the Sun to produce the amount of energy that it does. Each second, the Sun’s lost mass is about 5 million metric tons. When compared to the Sun’s total mass, the amount lost through nuclear fusion is almost insignificant. Therefore, we don't see the Sun decreasing in size.
Are the brightest comets those closest to the sun or those farthest from the sun?
The brightness of a comet is not determined by its distance from the sun, but rather by factors such as the size of its nucleus, how recently it has passed close to the sun, and how much dust and gas it is releasing. Therefore, the brightest comets can be found at various distances from the sun.
Which planet is the closest in size to the sun?
Since the Sun is much bigger than all the planets, the biggest planet is closest in size to the Sun.
The physical size of an atom is largely determined by?
The physical size of an atom is largely determined by the size of the electron cloud.
How is eggs size determined?
It is determined by the weight not the height

The size of a planet's orbit is determined by?
The size of a planet's orbit is primarily determined by its distance from the star it orbits, as well as the planet's mass and the characteristics of the star. The orbiting planet's velocity and gravitational interactions with other bodies in the system also play a role in determining the size of its orbit.
How have scientist determined how the Sun will die?
no
Do planets get bigger as they get farther away from the sun?
No, planets do not get bigger as they move farther away from the sun. A planet's size is determined by its mass and composition, which remain relatively constant regardless of its distance from the sun. The distance from the sun influences a planet's temperature and orbital dynamics, but not its physical size.
The imaginary line between a planet and the sun?
The imaginary line between a planet and the sun is called the planet's orbit. This orbit is the path that a planet follows as it revolves around the sun, due to gravitational forces. The shape and size of the orbit is determined by the planet's velocity and distance from the sun.
Does the size of a planet affect the time it takes for one revolution around the sun?
The size of a planet does not directly affect the time it takes for it to complete one revolution around the sun, which is determined by its distance from the sun and the gravitational forces at play.

What does sloar mean?
of, relating to, or determined by the sun
Does a planet have less gravity if it is further away from the sun?
No. The surface gravity of a planet is a product of its size and mass. It has nothing to do with distance from the sun. However, a planet farther away from the sun will experience a weaker pull from the sun's gravity.
The volume of an atom is determined by the size of?
By the size of the atom and its mass
How are egg sizes determined?
The size of the egg is not determined by how big or small it is. They are sized by the unit measure as a whole.
