How much has the size of the Sun changed in the last few billion years?

This has been going on since soon after the Sun was formed 4.5 billion years ago.
then, Why is the Sun so big today 2021?
The Sun will also be slightly larger in our daytime sky. It’s a cosmic occasion called perihelion—the point of the Earth’s orbit that is nearest to the Sun. The word comes from the Greek words peri (near) and helios (Sun). … They’re entirely caused by the tilt of the Earth’s axis of rotation.
hence, How many Earths can fit in our sun?
The volume of the sun is 1.41 x 1018 km3, while the volume of Earth is 1.08 x 1012 km3. If you divide the volume of the sun by the volume of the Earth, you get that roughly 1.3 million Earths can fit inside the sun.
indeed Is there anything bigger than the sun?

How many Earths can fit in the biggest star?
Complete answer: We need to know that the diameter of VY Canis Majoris is 155000 times that of our Earth. Let us assume that nnumbers of Earth can be fitted into VY Canis Majoris. Therefore, we can conclude that 7.5477×1010Earths can be fitted into VY Canis Majoris.
What holds the Sun in place?
