The earth's diameter is 3.66 times that of the moon so just over three-and-a-half moons would fit across the earth,
If you're allowed to smash them into dust first, you could fit 15 Titans in the volume of the Earth, as the Earth's volume is 15.13 times Titan's. However, if they have to stay spheres, you can only fit 2 to 4, because you'll need to leave space between them. The diameter of Earth is 2.47 times the diameter of Titan, so you could definitely fit 2 side-by-side. The circumradius of 3 Titans in a triangle is √3/3*diameter+radius, which equals 2.15 times the radius of Titan, and Earth's radius is 2.47 times Titan's, so you could fit 3 Titans in a triangular shape inside Earth. It might be possible to fit 4 in a triangular pyramid shape, but you'll have to do the math. This topic is called "sphere packing"
The moons volume (our moon) is 2% of the earth volume, so if you could break it up into small chunks, you could fit it into earths volume 50 times. If you say that you cant break up the moon, and just fit whole moons into the earth with spaces, then you're looking at a lot less.

Eris is in the Kuiper Belt (like Pluto) and is 96.6AU away. (1AU=93 Million Miles and is the average distance from the Earth to the Sun)
1300 times.
960 times
Roughly 390 times.
Mercury is about 2.54 times smaller than the Earth.You could fit about 16.38 Mercury's inside the Earth
The Moon is about 1/6th the size of Earth, so you could fit approximately 6 moons across the Earth's surface.
About 1.3 million suns could fit inside the Earth's volume.
1,000,000,000 is how many times it could fit into the sun.
The earth's diameter is 3.66 times that of the moon so just over three-and-a-half moons would fit across the earth,
Jupiter's diameter is approximately 11 times that of Earth. Therefore, you can fit nearly 11 Earths across the diameter of Jupiter.
Mercury is smaller than the earth so you can't. Also mercury has no moons.
Pluto isn't larger then earth in fact you can fit 4 plutos in earth
