It is impossible for an object to stay (from earth's perspective) 'behind' the sun, unless it is on the exact opposite orbit whilst orbiting at the exact same speed as earth, even then we would know it was close due to perturbations in all the other planets orbits.
So the argument that it is staying behind the sun is moot, therefore the need to see it during the day and near the sun is moot because it will move away from the sun at some point.

1 FOR THE SUN
1 FOR MERCURY
1 FOR VENUS
It's nearly 300 million miles away and barreling toward us. The intruder from deep space, called called comet Elenin, crosses Earth's orbit on its inbound leg and again on its outbound swing around the sun later this year.
Russian astronomer Leonid Elenin discovered the innocuous little comet on Dec. 10, 2010, at International Scientific Optical Network's robotic observatory near Mayhill, New Mexico.
Presently the comet is a faint smudge of light in deep sky exposures. By late August comet Elenin should be visible to the naked eye as a dim "fuzzy star" with a tail. Over a few weeks the visitor will speed across the spring constellation Virgo and toward Leo on its outbound leg.
I've found that the best way to spot Venus in the daytime is to first note the angular distance between the Sun and Venus by observing Venus shortly after sunset. Then, the next day, find an observing site where the Sun is blocked from view (essential both for eye safety and to allow the iris to dilate and see Venus better against the sky). From that location, sweep the sky in overlapping fields with binoculars pre-focused at infinity by observing an object on the horizon. Sweep along the ecliptic in the area with the angular separation from the Sun noted the previous night. Since the Sun is blocked from view at your observing site, you can freely scan the sky without fear of damaging your vision by inadvertently sweeping past the Sun.
When you sweep past Venus, you'll know it. Even with my battered, poorly collimated, and cheap 6×30s, Venus is a brilliant speck of white against the blue sky. Once you've found Venus with binoculars, put the binoculars down and observe that area of sky with the naked eye. If the sky is perfectly clear your eye has no reference to focus upon so if you've learned the trick of consciously focusing your eyes, changing the focus may help Venus pop out from the sky
ote that asteroid 2009BD is highlighted in red because it will pass less than one lunar distance close to Earth.You cannot hide something in the sky.

Ok try this quick animation I just did then.
Yellow circle is the sun.
Blue dot is earth
Red dot is object hiding from earth's view behind the sun.
Do you see what I mean by it having to have an identical, opposite orbit?
Then there is the fact that the common theory about Nibiru is that it has an elliptical orbit, this makes the likelihood of it hiding behind the sun even less.
Then there is also the fact that there are plenty of satellites that a facing the sun front and back all day every day, in fact just recently the two STEREO craft aligned with the sun perfectly so that were looking at it front and and back at the same time.
So in all reality there is no hiding behind the sun.
And finally to reiterate and add to the above orbit diagram, this is what the inner planets (Mercury, Venus, Earth and Mars) orbiting the sun:
