Why isn't a galaxy size alone useful in determining its distance from earth earth?

The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.

What planets stars comets are in Galaxy NGC 3370?
Who knows. We are only just able to determine planets in our own galaxy, let alone others. We have detected a supernova, producing SN 1994ae in that region of space.
Until 2050 can we discover life on other planets?
It is likely to discover new animals and species because we are not alone in this whole wide galaxy.
Does the universe have more than one black hole?
The universe definitely has more than one black hole. Just in our galaxy alone there's an estimated 100 million of them, and the observable universe has at least 100 billion galaxies.
Why does it take so long to get to other planets?
Sheer distance. We are talking about millions and millions of miles alone between Earth and Mars. When you factor in the distance between other planets, like from Jupiter to Saturn, the expanse of space only grows. It takes time to travel that far.

How does One know that he is not alone is the universe?
Although it's impossible to know, one has to think about the vastness of our Universe and that it contains an estimated 100 to 200 billion galaxies - our galaxy is one among billions. If that doesn't blow your mind, our galaxy is 100,000 light years in distance - and a single light year equals about 6 trillion miles. Now, think about the distance between one galaxy to the next...trillions upon trillions of miles. Is it truly logical to think that we're the only forms of life in our Universe? I don't think so.
Are you alone in the galaxy?
No. There are Lumas, sometimes Toads, occasionally Luigi/Luigi's ghost and of course enemies.
Is there more than one blue star?
Yes. Millions of blue stars exist in our galaxy alone.
Are there other stars similar to the Sun?
The Sun is a G-type star. There are millions of them throughout our galaxy alone.
Is Earth the only planet in the universe?
No, there are thought to be billions of planets just in our galaxy alone. Then there are billions of galaxies. There are 7 other planets in our own solar system alone.
What galaxy shape the Milky Way?
The Milky Way Galaxy is classed as a spiral galaxy as it's appearance is of a spiral with looser outer stars becoming denser the closer you get to the centre. As a picture is worth a thousand of my words, the the related link for a generated picture of our galaxy. Note: This is a computer generation of what we believe the galaxy looks like and not a real one (as we have not ventured past our own solar system, let alone the galaxy).
