Our current space missions, such as NASA's TESS and ESA's CHEOPS, are designed to search for exoplanets that are similar in size and orbit to Earth. These missions will provide us with more data on exoplanets and their systems, which may help us identify systems that are similar to ours. However, it may take a decade or two to gather enough data to confirm whether any exoplanetary systems are truly like ours.
