The current limit to distances we can measure via parallax is about 1000 light years, which means that we cannot accurately measure the distances of objects beyond that distance using parallax. The upcoming Gaia mission is expected to greatly improve our ability to measure distances using parallax, extending the limit to tens of thousands of light years.
