If this bogus planet is visible near our sun but around the orbit of Mars, wouldn't that put it on the OTHER side of the sun?

I mean, wouldn't it be around 200 million miles away, at least?

And at that distance wouldn't it have to be traveling at nearly 500,000 MPH in order to get here inside the next 17 days?

And what would its perigee be? Assuming it actually can stay in an orbit at that velocity.
