322,900
The suns mass is 332,950 earths.
No, it is only a tiny fraction. The sun's mass is roughly 330,000 times greater than the Earth.
Mars is the fourth closest planet to the sun, after Earth, but before the asteroid belt (which comes before Jupiter). Mars is 227,936,640 km (141,633,263 miles) from the sun on average, around 1.5 times the Earth to sun distance. Mars is the furthest of the four inner, terrestrial planets from the sun.
the sun because its mass is way bigger than that of earths
About 333,000 Earth masses would equal the mass of the sun. Additionally, 1,300,000 Earths would fit inside the Sun.
Sun, the Sun is the Earths 'star'
Mercury's mass = 0.055 x Earths, Volume = 0.056 x Earths Mars' mass = 0.1075 x Earths, Volume = 0.151 x Earths Venus' mass = 0.815 x Earths, Volume = 0.857 x Earths (Earth) mass = 1 x Earths, Volume = 1 x Earths Uranus' mass = 14.536 x Earths, Volume = 63.086 x Earths Neptune's mass = 17.147 x Earths, Volume = 57.74 x Earths Saturn's mass = 95.152 x Earths, Volume = 763.59 x Earths Jupiter's mass = 317.8 x Earths, Volume = 1321.3 x Earths
Mercury's mass = 3.30 x 1023kg or 0.055 x Earths Venus' mass = 4.87 x 1024kg or 0.815 x Earths Earth's mass = 5.97 x 1024kg or 1 x Earths Mars' mass = 6.42 x 1023kg or 0.1075 x Earths Jupiter's mass = 1.90 x 1027kg or 317.8 x Earths Saturn's mass = 5.69 x 1026kg or 95.152 x Earths Uranus' mass = 8.68 x 1025kg or 14.536 x Earths Neptune's mass = 1.02 x 1026kg or 17.147 x Earths
If Earth's mass increased by four times, the speed of its orbit around the Sun would not change significantly, as orbital speed is primarily determined by the gravitational pull of the Sun and the distance from it. According to Kepler's laws of planetary motion, the speed of an orbiting body depends on the mass of the central body (the Sun, in this case) and the distance from it, not the mass of the orbiting body itself. Therefore, while Earth's mass increase would affect its gravitational influence on nearby objects, it would not alter its orbital speed around the Sun.
The core is 33% of the Earths mass
using the tables in the links below (and a little math), to match the diameter of the Sun would take about 109 Earths, to match the mass of the Sun it would take about 332,948 Earths, to match the volume of the Sun it would take about 1.3 million Earths (I think the hexagonal packing method is used here, cubic packing would be a few thousand less)
